Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in heritable traits of a population over time. The term "natural selection" was popularised by Charles Darwin who compared it with artificial selection, now more commonly referred to as selective breeding.
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.
