A cell has two pairs of submetacentric chromosomes, which we will call chromosomes IA, IB, IIA, and IIB (chromosomes IA and I B are homologs, and chromosomes IIA and IIB are homologs). Allele M is located on the long arm of chromosome IA and allele m is located at the same position on chromosome IB. Allele P is located on the short arm of chromosome IA, and allele p is located at the same position on chromosome IB. Allele R is located on chromosome IIA and allele r is located at the same position on chromosome IIB.

A. Draw these chromosomes, identifying alleles M, m, P, p, R, and r as they would appear in metaphase I of meiosis. Assume there is no crossing over.

B. Taking into consideration the random separation of chromosomes in anaphase I, draw the possible types of gametes that might result from this cell’s undergoing meiosis. Assume that there is no crossing over.

Answers

Answer:

A) Allelic position in the chromosomes:

IA  ----------M------------:-----------P----

IB  ----------m------------:-----------p----

IIA -----------------R--------------------:---------------------

IIB -----------------r---------------------:---------------------

B) Types of gametes (assuming there is no crossing over):

MPR; MPr; mpR; mpr.

Explanation:

In submetacentric chromosomes, the centromere is located near to the middle of the chromosomes.

Since these two pairs of homologous chromosomes do not undergo crossover, the resulting gametes after meiosis may have four (4) allele combinations.

Shortly after a stream dried up, you noticed a change in the field mouse population coat color variation. When the stream was flowing, there were two populations, one with darker coats and one with lighter coats. After the stream dried up, mice with darker coats were being born into the lighter coat population and vice versa.

a. True
b. False

Answers

Answer:

a. True

Explanation:

When the stream dried up darker coat mice were seen into the lighter coat population and vice versa because of the natural selection process.

Mice change their coat color by adapting the changes in the stream flow and evolve their coat either dark or light that provides camouflage so predators won’t see them and they are able to survive in the environment. Mice have the advantage of surviving long and they are able to pass their genes to the offspring.

Which phase the cell cycle would the cell stop in if you disrupted:_______.
1. the protein DNA polymerase S phase.
2. the depolymerization of the microtubules metaphase.
3. the polymerization of actin cytokenesis.
4. the protein ligase S phase.
5. the chiasmata formation.

Answers

The interphase (G1, S, and G2 phases) precedes meiosis (Meiosis 1 and meiosis 2). Immediately after meiosis, cytokinesis occurs.

1: S phase / 2: Anaphase 1 and 2 / 3: cytokinesis / 4: S phase / 5: Prophase 1.

---------------------------------

The interphase occurs before cell division. It is composed of the G1, S, and G2 stages.

During the S stage occurs the DNI replication process. At this point, also happens the synthesis of histones and other associated proteins. This is the only stage where the DNI molecule is replicated.

Among the enzymes involved in the DNA replication process, two of them are  

DNA polymerase III

•  Responsible for DNA elongation by adding nucleotides to the growing chain, from 3' to 5' extremes.

•  It includes only nucleotides that complement the original strand.

•  They need to recognize a primer to begin.  

DNA polymerase I eliminate ARN primers and substitute them with DNA.

DNA ligase seals the gaps that remain after replacing the primers by reestablishing phosphodiester bonds. They also bind the Okasaki fragments during the discontinuous strain synthesis.

1. the protein DNA polymerase  >>>>>>>  S phase.

4. the protein ligase  >>>>>>>  S phase.

                               ****************************************************

Through Meiosis, a diploid cell (2n) produces four haploid daughter cells (n).

After DNA replication there are two meiotic phases.

The first one is a reductive phase, in which homologous chromosomes separate.  In the second phase, the cell suffers a new, not reductive division.  

During prophase 1 of meiosis, each chromosome carefully pairs with its homologous chromosome.  

Crossing-over is the interchange of genetic information between two homologous chromosomes, making the daughter cells genetically different from the original one.  

The point where the interchange of genetic information occurs is the chiasma.  

5. the chiasma formation >>>>>>> propahase I

                          ****************************************************

Antiparallel microtubules between the separating chromosomes compose the spindle apparatus.

These fibers get elongated during the anaphase, while chromosomes or chromatids migrate to the opposite poles of the cell.

The depolarization of the microtubules drives the chromosomes or chromatids to segregate during the anaphase.

2. the depolymerization of the microtubules >>>>>> anaphase I and II

                          ****************************************************

Actin is a globular protein. Actin filaments are composed of the polymerization of the protein.

Among their many functions, actin polymers are involved in cytokinesis.

The final strangulation of the cytoplasm during the division process occurs through the organization of actin filaments.

Filaments form a ring structure, which progressively narrows its diameter until the complete separation of the two daughter cells.

3. the polymerization of actin >>>>>>> cytokenesis

                            *******************************

1. the protein DNA polymerase >>>>>>>>> S phase.

2. the depolymerization of the microtubules >>>>>>>>> anaphase I and II.

both ethanol and glycine are small molecules of approximately equal molecular weight. However, ethanol is much more membrane permeable than glycine. What accounts for the large difference in membrane permeability between ethanol and glycine

Answers

Answer:

Ethanol is a non polar molecule.Therefore it passes through the cells membrane easily by diffusion like other non polar like CO2 and water.However, glycine is an amino acid ( the simplest amino acid) a charged molecule /polar molecule/.it can not therefore pass through the bilayer by simple diffusion because of the phospholipid bi-layers. Therefore special transport proteins are needed for its passage across the cell membrane.

Example-GLYT 1 and 2 are the carrier proteins  specific for glycine transport across the membrane.

Industrial melanism refers to the dark pigmentation that evolved in some insects giving them protective coloration on vegetation darkened by soot in heavily industrialized areas prior to air pollution regulation. Assume that in one heavily polluted area near Birmingham, England in 1956, 79% of the moths of the species Biston betularia were black due to the presence of a dominant gene for melanism. Estimate the frequency of the dominant allele in this population, and the proportion of black moths that are heterozygous.

Answers

Answer:

The frequency of the dominant allele, p =  0.542The proportion of black moths that are heterozygous 2pq = 0.496

Explanation:

According to Hardy-Weinberg, the allelic frequencies in a locus are represented as p and q, referring to the allelic dominant or recessive forms. The genotypic frequencies after one generation are p² (Homozygous dominant), 2pq (Heterozygous), q² (Homozygous recessive). Populations in H-W equilibrium will get the same allelic frequencies generation after generation. The sum of these allelic frequencies equals 1, this is p + q = 1.

In the same way, the sum of genotypic frequencies equals 1, this is

p² + 2pq + q² = 1

Being

p the dominant allelic frequency,q the recessive allelic frequency,p² the homozygous dominant genotypic frequencyq² the homozygous recessive genotypic frequency2pq the heterozygous genotypic frequency

In the exposed example, 79% of the moths of the species Biston betularia were black due to the presence of a dominant gene for melanism.

If the genotypic frequency of back moths is 0.79, then, by performing the following equation we can get the not-black moths genotypic frequency:

p² + 2pq + q² = 1

where p² is the homozygous dominant genotypic frequency, q² the homozygous recessive genotypic frequency, and 2pq is the heterozygous genotypic frequency.

As 0.79 is the phenotypic frequency of black moths, then this frequency equals p²+2pq.

Clearing the equation:

p² + 2pq + q² = 1

0.79 + q² = 1

q² = 1 - 0.79

q² = 0.21

The genotypic frequency of non-black moths is 0.21. So, from here we can calculate the allelic frequency:

q² = 0.21

q= v 0.21

q = 0.458

If 0.46 is the allelic frequency of non-black moths, then by clearing the equation p + q = 1, we can get the p allelic frequency:

p + q = 1

p + 0.458 = 1

p = 1 - 0.458

p = 0.542

The genotypic frequency p² = (0.542)² = 0.294The heterozygote genotypic frequency

        2 x p x q = 2 x 0.542 x 0.458 = 0.496

Finally, we can check this answer by clearing the following equation:

p² + 2pq + q² = 1

0.294 + 0.496 + 0.21 = 1                  

The woman marked with a question mark is your friend. Knowing that you are taking Genetics, she comes to ask you for advice: she wants to have children, but is afraid that they will be sick with the disease. Her husband and her mother have no family history of HD. What is the probability that she is sick? What is the probability that her children will be, without knowing her own status regarding the disease?

Answers

Answer:

Explanation:

The woman with the question mark is not sure if she has the HD disease,

The mother had no history of the disease this means she is not a carrier of the disease but we are not sure of the fathers genotype.

If the father is a carrier in an homozygous dominant form(aa) and the mother does not have the disease her. gentotype is AA

A A ×aa

Aa Aa Aa Aa This means all their offspring will be Carrier of the disease because each parents contributes 50% of the gene their offspring is made of.

The probability that she is sick is 0% but she could be a carrot of the disease in an heterozygote form

If the woman who is a carrier (Aa)of the disease marries a man with no history of the disease(AA)

Aa ×AA

I

AA AA Aa Aa

The probation of their offspring being a carrier in heterozygous form is 50% while the probability of the offspring being dominant of the disease is 0%. Hence, she should not be afraid since her mother and husband who could have contributed to determining the gene of this offspring are not carriers of this gene the offspring are safe.
