Which statement best describes codominance and incomplete dominance?
Answer:
This question lacks options, the options are;
A) In codominance and incomplete dominance, both of the alleles are dominant.
B) In codominance and incomplete dominance, neither of the alleles are dominant.
C) In codominance, both of the alleles are dominant; in incomplete dominance, neither of the alleles is dominant.
D) In codominance, neither of the alleles is dominant; in incomplete dominance, both of the alleles are dominant.
The answer is C
Explanation:
Codominance and incomplete dominance are both a type of non-mendelian inheritance pattern i.e. patterns of inheritance that do not follow mendelian principles.
- In codominance, the alleles of a gene are both dominant and hence, both express themselves simultaneously for that trait. An example is the alleles A and B of the blood group in humans where both A and B are dominant in the gene.
- In incomplete dominance, neither of the two alleles of gene is dominant and none is recessive either. This means that the two alleles blend together to form an intermediate phenotype in a heterozygous offspring. An example is the pink flower in four o'clock plants resulting from the blending of red and white alleles.
Answer:
The correct answer is b
What is the difference between aggression and courtship?
Answer:
How you approach and talk to the person you like
Explanation:
If you go up and start saying inappropriate things or immediately try to kiss them then that is aggression. But if you go up and give them a subtle and light compliment like ''Hey I like your shirt" and start a conversation, maybe at the end ask (not demand) for her number, then that is a courtship. P.S.If you say something like give me your phone number, that is aggression.

People can be immunised against a pathogen through vaccination. Different vaccines are needed for different pathogens. For example, the MMR vaccine is used to protect children against measles, mumps and rubella (German measles).
What is the exchange of genes between
homologous chromosomes called?
A Crossing over
B. Independent assortment
C. Criss-Crossing

In cats, white spots are caused by a dominant allele called T, while (tt) individuals are solid colored. Also short hair(H) is dominant to long hair(h). What would the probability be of getting a white-spotted, long-haired cat from this cross: TTHh x Tthh? What are the phenotypes of the parents?
Answer:
1. Probability is 1/2
2. Parents phenotypes:
TTHh = white spots, short hair
Tthh = white spots, long hair
Explanation:
This question involves two different genes coding for spot color and hair length in cats respectively. In the first gene, the allele for white spots (T) are dominant over the allele for solid color (t) while the allele for short hair (H) is dominant to long hair (h).
According to this question, a cross between parent cats was performed as follows: TTHh x Tthh. The following gametes will be produced by each parent:
TTHh - TH, Th, TH, Th
Tthh - Th, Th, th, th
Using these gametes in a punnet square (see attached image), 16 possible offsprings will be produced. However, according to the question, 1/2 of the offsprings will probably be white-spotted and long-haired. The phenotypes of the parents are as follows:
TTHh = white spots, short hair
Tthh = white spots, long hair

Describe the three components that make up the structure of the atom, including their charge and specific locations within atom.
The three components that make up the structure of the atom are as follows:
Electrons (Negatively charged sub-atomic particles). Protons (Positively charged sub-atomic particles).Neutrons (Neutrally or no charge). What is the nucleus of an atom?The nucleus of an atom may be defined as the center of any atom that significantly consists of protons and neutrons.
Due to the positive charge on protons and neutral charge on neutrons, the nucleus of an atom is found to be positively charged.
The electrons are negatively charged sub-atomic particles which are always revolving around the nucleus of an atom.
While protons are positively-charged sub-atomic particles that are present in the nucleus of an atom. And Neutrons are neutral or no charge sub-atomic particles that are present in the nucleus of an atom along with protons.
Therefore, the three components of atom has been significantly described with respect to their charge and specific locations within atom.

If you see caddis fly larva and freshwater shrimp, what is the quality of the water?
Answer:
The water quality is good because they are both sensitive to pollution
Explanation:
The quality of the water is extremely fine when you see caddis fly larva and freshwater shrimp.
How do you determine the quality of water?The quality of water is determined by analyzing several properties like dissolved oxygen, pH, suspended particulate matter, pollution estimation, density, etc.
The member of caddis fly larva and freshwater shrimp always found in the aquatic environment where there is less or no pollution.
These species are adapted to the freshwater ecosystem and hence commonly found in fine quality of water.

Explanation:
A young goat has downward-curved horns. Its father has upward-curved horns while its mother has downward-
curved horns. Which of these statements explains why the young goat has downward-curved horns?
1. The young goat inherited one copy of the gene for horn shape from mother and one copy from its
father. That gene combination instructs for proteins that connect in ways that make downward-curved
horns.
2. The young goat inherited one copy of the gene for horn shape from its mother and one copy from its
father. Those genes connect together to make its downward-curved horns.
3. The young goat inherited its copies of the gene for horn shape from its mother and not from its father.
Just like its mother's genes, those genes instruct for proteins that connect in ways that make its
downward-curved horns.
4. The young goat inherited its copies of the gene for horn shape from its mother and not from its father.
Those genes connect together to make its downward-curved horns.
The young goat inherited its copies of the gene for horn shape from its mother and not from its father.

Answer:
You gotta sketch out a sperm egg under the questions after the example.
Explanation:
You see, there is an example, right? Well, then, depending on how many chromosomes there are, write the correct chromosome number in each cell. Number 1 is just an example of what you gotta do. Mosquito wing cell contains 6 chromosomes. The cell contains at least 42 chromosomes. Do what you saw in the example: egg cell gamete + cell gamete = 1st somatic cell.
