Burka [1]

Hello! Your answer is the bottleneck effect.

Speaking more broadly, genetic drift is when a population becomes smaller, and there are fewer genotypes in the gene pool. There are two types of genetic drift: the bottleneck effect and the founder effect.

The bottleneck effect is when an environmental change / human activity causes many members of the population to die, which means that the gene pool is now represented by just a few organisms. This is correct in this scenario, as an environmental change caused the gene pool to be reduced.

The founder effect is when a new colony is established elsewhere, so only alleles in the smaller founder group will be reproduced.

Hope this helps!

Represents exponential growth
Svetllana [295]

Answer:

The variable b represents the growth or decay factor. If b > 1 the function represents exponential growth. If 0 < b < 1 the function represents exponential decay. When given a percentage of growth or decay, determined the growth/decay factor by adding or subtracting the percent, as a decimal, from 1.
