Sometimes domesticated plants and animals are released into the wild, where they breed, survive, and populate. Which of the following statements is true?
A. Because populations are heavily monitored by humans for disease there are few deleterious alleles found in most domesticated populations.
B. They tend to perform very well as often the traits chosen for by humans have created bigger, stronger, and healthier populations that outcompete wild ones.
C. There appears to be little difference between long-term survival of domesticated and wild species when both are left in the wild.
D. Because domestic populations often come from a few individuals, deleterious alleles are allowed to drift to a high frequency which inhibits their ability to survive in the wild.
Ans: D. Because domestic populations often come from a few individuals, deleterious alleles are allowed to drift to a high frequency which inhibits their ability to survive in the wild.
