Homework Answers
Answer: Option 3 is correct
Explanation:
Colour-blindness is an X-linked recessive disorder
Males are more affected for an X-linked recessive disorder as they
contain only one X-chromosome.
Females are less affected for an X-linked recessive disorder as
they contain two X-chromosome.
The frequency of Colour-blindness in males in the given
population = 8%
Number of males = 2000
Affected males = 2000 X (8/100)
= 160
The number of affected females will be less than the number of
affected males.

As you already know, sickle-cell anemia is caused by an autosomal recessive trait. One of your friends is seeking some genetics advice. They (Lia and Scott) are planning on having a child and want to know what the probability is that their child will have sickle-cell disease. Lia is phenotypically normal, but we do not know anything about her family history. Scott's sister has sickle-cell disease,...

Please answer genetics questions 9 and 10
The following is the genetics of determination of blood type in human. How many alleles are ever known that are involved in determination of blood type? How many alleles we as individual can we have in our DNA? Is this a typical example of monogenic trait? Digenic trait? Or trigenic trait? Is only one gene involved? Is A dominant over B allele? Is A dominant over O allele? Is B dominant over O...

You are examining snacking behavior in your dorm. You've determined that late night snacking is a dominant trait (M_) compared to people that actually get sleep (mm). You genotype (with permission, of course!) all of the students in your dorm and get the following results: MM = 67, Mm = 23, and mm = 10. Which of the following statements is true about your dorm population?...

Question 2:
You are a population geneticist interest in the frequency of the sickle-cell allele in a small town in Sudan. From hospital records you know that people in the previous generation had 4% incidence of sickle-cell anemia. Assuming Hardy-Weinberg equilibrium, what is the expected frequency of the sickle-cell allele in the current generation, and what is the predicted frequency of heterozygotes in the population? Consider a woman who suffers from Menkes Disease, an X-linked recessive disease. Her...

12. A small portion of deer have a trait called leucism, which is white coat. The frequency of the leucitic phenotype is 0.00005 (or 1/20,000). Leucism is recessive to wild type color. Assuming that the deer population is in Hardy-Weinberg equilibrium fr A. Estimate the frequencies of the recessive leucistic allele (I) and the dominant wild type allele (L) B. Estimate the frequency of deer with heterozygous genotype C. For the calculations above, you assume...

1. Which of the following is FALSE? A. If a genetic disease reduces fertility and the allele that causes the disease offers no other advantage, the allele will likely eventually disappear, due to natural selection. B. Natural selection does not favor individuals who are homozygous for the sickle-cell allele, because these individuals typically die before they are old enough to reproduce. C. Individuals who are heterozygous HbA/HbS are protected from malaria, and this is why sickle-ce disease persists in wetter,...

Show all your work for full credit. Take all calculations out to 5 decimal points. Circle your final answer. Write legibly! Sickle cell anemia affects populations differently. While 80,000 Americans overall out of 3.25 million Americans have the disease, sickle cell anemia is estimated to occur in 1 in 500 African Americans and 1 in 1,400 Hispanic Americans. What is the frequency of the b allele in African Americans? What is the frequency of b in Hispanic Americans?
