Question

The most common form of color blindness, known as red–green blindness, is an X-linked recessive trait affecting about 8% of the male population in the United States. What proportion of females would you expect to have this trait, and what proportion would you expect to be carriers?

Answer 1

Answer:

A) Proportion of females with the trait is less than 8%

B) Proportion of females that would be carriers is greater than 8%

Explanation:

Only the 8% male sufferers can give their diseased X-chromosome for the female XX to be formed. hence, the proportion of the female carriers is most likely greater than 8%

On the other hand, the proportion of female sufferers will be definitely less than 8%, for 92% of the remaining male population are neither carriers nor sufferers; and the 8% male sufferers are strictly needed to give the disease X-chromosome for a female to have the trait XX.
