Gene flow is the transfer of genetic material from one population to another. An example is a deer, which tends to leave its original herd to find mates in new herds. If a deer finds a mate in a new herd and reproduces successfully, which of these MOST likely occurs?Select one:a.Mutations increaseb.Genetic diversity increasesc.Genetic drift decreasesd.Behavioral isolation decreases
Question
Gene flow is the transfer of genetic material from one population to another. An example is a deer, which tends to leave its original herd to find mates in new herds. If a deer finds a mate in a new herd and reproduces successfully, which of these MOST likely occurs?Select one:a.Mutations increaseb.Genetic diversity increasesc.Genetic drift decreasesd.Behavioral isolation decreases
Solution
The most likely occurrence in this scenario is b. Genetic diversity increases. Here's why:
Gene flow, as defined in the question, is the transfer of genetic material from one population to another. When a deer leaves its original herd to find mates in a new herd, it introduces its own unique genetic material into the new population. If it reproduces successfully, these genes are passed on to the offspring, thereby increasing the genetic diversity within the new herd.
This is because the offspring will have a combination of genes from both parents, which may include genes that were not previously present in the new herd. This increase in the variety of genes within the population is what we refer to as an increase in genetic diversity.
So, the correct answer is b. Genetic diversity increases.
