Answer: the different thing about eachother is that one will have more and weight more than the other

Explanation:

The organelle that stores the information that determines an individual's hair color is the nucleus. The genetic information or DNA, which contains the instructions for making proteins including those that determine hair color, is stored in the nucleus of cells.

The nucleus is the organelle that contains the data that establishes a person's hair color. Chromosomes in the nucleus include genes that are responsible for a number of characteristics, including hair color. Melanin, the pigment that gives hair its colour, is produced according to the instructions provided by these genes. Blonde, brown, black, or red hair can all be produced by different variations of these genes. Therefore, each cell's nucleus contains DNA, which contains the information about hair color.

Answer:

The answer would be extirpation.

Explanation:

The term for when a species no longer exists in a specific portion of their range but can be found elsewhere is extirpation.

The pair of terms that correctly matches a cell or group of cells with its ability to differentiate into different specialized cells is a) fertilized egg: pluripotent.

Pluripotent cells have the ability to differentiate into almost any cell type in the body, including cells of all three primary germ layers: endoderm, mesoderm, and ectoderm. The fertilized egg, or zygote, is the earliest stage of development and is considered pluripotent because it has the potential to differentiate into all the cell types of the body.

Totipotent cells have the ability to differentiate into all cell types, including embryonic and extraembryonic tissues. Ectoderm is one of the three primary germ layers that gives rise to various tissues, including the skin and nervous system. It is not totipotent but is rather multipotent, meaning it can differentiate into a limited number of cell types.

Endoderm and mesoderm are also primary germ layers that give rise to various tissues and organs in the body. Endoderm is multipotent, meaning it can differentiate into a limited number of cell types, while mesoderm is pluripotent, meaning it has the potential to differentiate into a wide range of cell types.

Allelic and genotypic frequencies remain the same through generations in a population that is in H-W equilibrium. Frequency of dominant allele: 0.52. Frequency of recessive allele: 0.48. % homozygous dominant: 27%. % heterozygous: 50%. % homozygous recessive: 23%

The Hardy-Weinberg equilibrium is a theory that states that the allelic and genotypic frequencies in a population in equilibrium remain the same generation after generation.

Populations in H-W equilibrium are not evolving.

Assuming a diallelic gene,

The addition of the allelic frequencies equals 1

p + q = 1.

The genotypic frequencies after one generation are

The sum of genotypic frequencies equals 1

p² + 2pq + q² = 1

In the exposed example, the frequency of the homozygous dominant genotype is given.

p² = 27% = 0.27

From this information, we can get the frequency of the dominant allele by taking the root square of the value.

p² = 0.27

p = √0.27

p = 0.52

Now, we can clear the equation p + q = 1 and the get recessive allele frequency.

p + q = 1

0.52  + q = 1

q = 1 - 0.52

q = 0.48

Now, we can get the frequency of the homozygous recessive genotype and the heterozygous one.

q = 0.48

q² = 0.48²

q² = 0.23

2pq = 2 x 0.52 x 0.48

2pq = 0.5

p² + 2pq + q² = 1

0.27 + 0.5 + 0.23 = 1

No, it is not possible to produce a line of pure-breeding gray wolves. The reason is that gray coat color results from the incomplete dominance of the white coat and black coat alleles.

Incomplete dominance occurs when the traits of two alleles blend together, resulting in a different phenotype than either parent.
No, it is not possible to produce a line of pure-breeding gray wolves. The reason is that gray coat color results from the incomplete dominance of the white coat and black coat alleles.
When a wolf is heterozygous for these two alleles (one white coat allele and one black coat allele), it displays a gray coat. To create a line of pure-breeding gray wolves, you would need both alleles to be gray. However, gray is not a separate allele; it is the result of incomplete dominance between white and black coat alleles.

Therefore, any mating of gray wolves would still produce offspring with a mix of white, black, and gray coat colors, depending on the combination of alleles passed down to the offspring.

The axon terminal of the neuron carrying somatic sensory information from an afferent presynaptic neuron can be found in the thalamus of the brain. The answer is a)

The somatic sensory information from the body is carried by the dorsal root ganglia of the spinal nerves to the spinal cord. From there, the information ascends the spinal cord via two pathways: the dorsal column pathway, which carries information about fine touch discrimination and proprioception, and the anterolateral pathway, which carries information about pain, temperature, and crude touch.

These pathways eventually synapse in the thalamus of the brain, which acts as a relay station for sensory information. The axon terminal of the neuron carrying somatic sensory information from an afferent presynaptic neuron can be found in the thalamus because all somatic sensory information that reaches the cerebral cortex is first processed there.

It is important to note that somatic sensory information from the left side of the body projects to the right side of the somatosensory cortex, and vice versa. Hence, a) is the correct option.

The chi-square value for the observed genotype frequencies for a population of 100 lizards is approximately 161.63.

To find the chi-square value for the observed values of the genotypes (AA = 75, Aa = 15, aa = 10) in a population of 100 lizards, we need to compare them with the expected values under a specific hypothesis.

First, we need to determine the expected genotype frequencies based on a specific hypothesis or assumption. Let's assume that the population is in Hardy-Weinberg equilibrium, which assumes random mating and no evolutionary forces at play. In that case, the expected genotype frequencies can be calculated based on the allele frequencies.

Let's assume that the allele frequencies are p and q, where p represents the frequency of the dominant allele (A) and q represents the frequency of the recessive allele (a). In a population in Hardy-Weinberg equilibrium, the expected genotype frequencies can be calculated as follows:

AA = p² * total population

Aa = 2pq * total population

aa = q² * total population

Since we don't have the allele frequencies, we cannot calculate the exact expected values. However, let's assume that the allele frequencies are p = 0.6 and q = 0.4.

Expected genotype frequencies:

AA = (0.6)² * 100 = 36

Aa = 2 * 0.6 * 0.4 * 100 = 48

aa = (0.4)² * 100 = 16

Now, we can calculate the chi-square value using the formula:

chi-square = Σ ((observed - expected)² / expected)

chi-square = ((75 - 36)² / 36) + ((15 - 48)² / 48) + ((10 - 16)² / 16)

chi-square = (39² / 36) + (33² / 48) + (6² / 16)

chi-square = 136.5 + 22.88 + 2.25

chi-square = 161.63

Therefore, the chi-square value for the observed genotype frequencies is approximately 161.63.

The probability of a child inheriting two mutated alleles (mm) and having cystic fibrosis is 1 out of 4, or 25%.

Cystic fibrosis (CF) is an autosomal recessive disease, meaning that an individual must inherit two copies of the mutated CF gene (one from each parent) to express the disease. When both parents are carriers of the mutated CF gene, they have a normal phenotype since they possess one functional copy of the gene.

The chances of two normal carrier parents having a child with cystic fibrosis can be determined using a Punnett square. In this genetic model, each parent contributes one allele (either normal or mutated) to their offspring. Since both parents are carriers, they have one normal (N) and one mutated (m) allele.

The Punnett square displays the four possible allele combinations for the child:
1. NN (normal, non-carrier)
2. Nm (normal, carrier)
3. mN (normal, carrier)
4. mm (affected by cystic fibrosis)

So, in this case, the chances of two normal individuals who are carriers of the cystic fibrosis gene having a child with the disease is 25%.

Answer:

A. The kittens inherited different genes for fur color from their parents.

Explanation:

This because the genotype of fur color is from parents, your literal genetic makeup. While phenotype is influenced by your surroundings.

Answer:

If the birth rate in a population is more than the death rate, then the population will grow over time. This means that there will be more individuals in the population and more demand for resources such as food, water, and space. If the birth rate in a population is less than the death rate, then the population will shrink over time. This means that there will be fewer individuals in the population and less competition for resources. However, if the population becomes too small, it may face extinction due to genetic drift, inbreeding, or environmental changes.

Me depend on the dominant gene, which can be predicted based on the parents' phenotypes.

The presence or absence of dimples is inherited as a dominant trait, meaning that if at least one parent has dimples, Me has a chance of inheriting the dominant gene and expressing the phenotype. If both parents have dimples, Me must have at least one copy of the dominant gene, making it highly likely that Me has dimples.

If neither parent has dimples, it is unlikely that Me has inherited the dominant gene. However, if one parent has dimples and the other does not, the probability of Me having dimples depends on whether the non-dimple gene is homozygous or heterozygous in the non-dimple parent.

In this question, 0.01 would be the fitness value of one female.

Here, correct option is D.

In a study of walrus mating habits, researchers observed a population of 75 offspring produced by the males and females of the species. The dominant male walruses were found to be the fathers of 50 of the offspring, while the smaller male walruses that mimicked female behaviors and hid among the female walruses were the fathers of 25 of the offspring.

Each of the 75 female walruses in the population produced only one offspring. From this information, we can deduce the fitness value of one female walrus in the population.

In this case, the fitness value of one female would be 0.01, as each female only produced one offspring, despite the fact that there were many more offspring produced by the males. This indicates that the females had a much lower reproductive rate than the males, and thus had a lower fitness value.

The process capable of producing a gamete with the alleles po in an organism with the chromosomes for olive body color and purple eye color on the same chromosome is crossing over or recombination.

Crossing over occurs during meiosis when homologous chromosomes exchange genetic material, resulting in new combinations of alleles on the chromosomes. This process can occur between the genes for olive body color and purple eye color if they are located on the same chromosome.

In the case of the diagram provided, the olive body color and purple eye color genes are located on the same chromosome, but they are not directly next to each other. This means that crossing over is possible between these genes, but the probability of a crossover event occurring between them is lower than if they were located closer together.

If a crossover event does occur between the olive body color and purple eye color genes, it can result in a gamete with the alleles po, which would be a new combination of alleles not present in either parent.
