Question

In a particular population of humans, there is a higher rate of polydactyly than in the general human population. The most likely explanation is:

Answer 1

A) bottleneck effect
B) founder effect
C) sexual selection
D) natural selection

Answer 2

solution is B but not sure how to distinguish between A and B given the context of the problem

Please do not comment unless you are making a serious attempt at an explanation.

Answer 3

There is a slight difference between the two effects. Bottleneck effect is when the population is reduced for a single generation. The founder effect is when a new colony is started by a few members of the original population. Essentially a new separate population.

Answer 4

If that makes sense?

Answer 6

The "founders" contained alleles for polydactyly and started the population. As the population grew this allele was probably common.

Answer 7

and descended through the generations

Answer 8

appreciate it.

Answer 9

thank you
