Questions

1. A hypothetical population of 10,000 humans has 6840 individuals with the blood type AA, 2860 individuals with blood type AB and 300 individuals with the blood type BB. Show work and answer

a. What Is the frequency of each/genotype in this population?

b. What is the frequency of the A allele?

c. What is the frequency of the B allele?

d. If the next generation contained 25,000 individuals, how many individuals would have blood type BB, assuming the population is in Hardy-Weinberg equilibrium?Show work and answer:

2. A population of birds contains 16 animals with red tail feathers and 34 animals with blue tail feathers. Blue tail feathers are the dominant trait

a. What is the frequency of the red allele? Show work and answer:

b. What is the frequency of the blue allele?Show work and answer:

c. What is the frequency of heterozygotes? Show work and answer:

d. What is the frequency of birds homozygous for the blue allele? Show work and answer:

3. 1 in 1700 US Caucasian newborns have cystic fibrosis. C is the normal allele, dominant over the recessive c allele .Individuals must be homozygous for the recessive allele to have the disease.

a. Assuming a Hardy-Weinberg Equilibrium, how many newborns would have cystic fibrosis in a population of 10,000 people? Show work and answer:

4. If 98 out of 200 individuals in a population express the recessive phenotype, What percent of the population are heterozygotes?) Show work and answer:

5. Brown hair (B) is dominant to blond hair (b). If there are 168 brown haired people in a population of 200: Show work and answer:

a. What Is the predicted frequency of hetero? otes?

b. What is the predicted frequency of homozygous dominant?

c. What is the predicted frequency of homozygous recessive?

1. A rather large population of foxes has 596 red-haired individuals and 557 - don brown-haired individuals. Assume that fed hair is completely recessive Please calculate the following:

a. Conditions happen to have been really good this year for breeding and next year there are going to be 11,245 young foxes. Assuming that all of the Hardy-Weinberg conditions are met, how many of these would you expect to be red-haired]AND how many would you expect to be brown-haired?

Show work and answer:

6. The ability to taste PTC is due to a single dominant allele "I". You sampled 215 individuals in a biology class, and determined that 150 could detect the bitter taste of PTC and 65 could not. Show work and answer:

a. What is the predicted frequency of the recessive allele (d)?

b. What is the predicted frequency of a dominant allele (I)?

c. In a population of 0,000 people, how many would be heterozygous (assuming Hardy-Weinberg equilibrium)? Homozygous dominant? Homozygous recessive?
