Question

A population of frogs lives on a remote island. The first frog that colonized the island had an unusual color pattern and now all of the frogs on the island have this color pattern. The explanation for this would be:

a. natural selection

b. gene flow

c. bottleneck

d. the founder effect

e. non-random mating

Answer 1

D) The founder effect

The founder effect is a type of genetic drift which occurs in a small population and not a natural selection involves that a group of organisms from an existing population leaves the original group and lives in somewhere from the original population and the progeny of the group that left the original population will increase in number and will have the characters that the group of people organisms that left from the original people and not of the original population .

In here, the first frog with unusual colour pattern left the original population and the progeny of the frog will have the characters of the frog with unusual colour pattern .
