Question

There is a large population of white, gray and brown rabbits that is getting rather crowded. One group of 5 white rabbits and 7 gray rabbits migrated to a smaller burrow close by, and another group of 3 white rabbits and 4 brown rabbits migrated further to a new forest. What is this an example of?

A. Bottleneck Effect
B. Founder Effect
C. Gene Flow
D. Mutation

Answer 1

Answer 2

I think Its B... But im so confused between B and A.

Answer 3

i'm not too sure about this xD Haven't studied this..
but it's definitely not mutation

Answer 4

I know.. its hard T_T. I know its not gene flow either, so its between A & B..

Answer 5

hmm i'll try to google both A and B to see what i can find xD

Answer 6

Haha ok thanks :D

Answer 7

This is what i've found:
Founder effect - when a few individuals become isolated from a larger population, this smaller group may establish a new population whose gene pool differs from the source population. This phenomenon is believed to contribute to the high frequency of inherited disorders among the isolated population.

Bottleneck effect - a sudden change in the environment (such as a fire or flood) may drastically reduce the size of a population. Ultimately, the survivors of such environmental changes exhibit a gene pool that differs from the original population. The bottleneck effect may result in some alleles being more prevalent than others, or, some alleles may be eliminated all together.
So i'm going to say that it is probaaably the founder effect because bottleneck effect results from a catastrophe or change in the environment (tsunami) occurs :)
