Hemophilia is an x-linked recessive trait. In a population of 2000 people, 4 women have hemophilia, 30 men have hemophilia, and 80 are carriers of the disorder. What is the frequency of the hemophilia allele? (Assume the population is 50% men and 50% women.) a.0.059 b.0.033 c.0.057 d.0.039 e.0.038 In a population of 15,000 individuals, 1350 express a recessive trait. How many heterozygotes are there expected to be? a.2100 b.3150 c.6300 d.1800 e.4200

In a certain population, one out of 25 people are color blind, on average. (a) If a random sample of 30 people is chosen, what is the probability that there is at least one color blind person? Hint: Find the probability that none of the 30 people is color blind. (b) Use the inclusion-exclusion formula to find the probability that in a random sample of two people (i.e., the people are independently chosen), at least one of the two is...

Fill in the blank. Hemophilia is an X-linked trait. In a population of 20,000 people in HW equilibrium, 10,000 women and 10,000 men were tested for this trait, and 15 men were found to have the disorder. The value that you calculated for the Hemophilia allele was (to 4 decimal places) _______ and there would be _______ carrier females in this population.
