8. In a population of 12,000 individuals, 300 men
are afflicted with a recessive, X-linked disease. How many woman
would be expected to be afflicted in this population? (Assume the
population is 50% men and 50% women.)
a. 30
b. 7.5
c. 60
d. 15
e. 3.75
Homework Answers
The nunber of male individuals in a population are 12,000/2=6,000
The male has XY chromosome.
300 male are affected out of 6,000 individual.
Genotypic or allelic frequency of disease allele is same in the men population = 300/6,000=0.05
The female individual afflicted with this disease are (0.05)^2×6,000= 15
Right answer is d)15

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.

10. Red green colorblindness is an X-linked recessive disease. That means that it is carried on the X chromosome, so men have just one copy of the gene while women have two. In women, both copies must be the recessive disease allele in order to show the disease phenotype, but because men only have one allele, just one recessive allele causes the disease phenotype. Matt and Kate both have normal vision, but Kate's father is colorblind. Use X for the...
