Question

What does a bottleneck event cause in a population?

a diverse population

the best traits to survive

many advantageous traits

a small gene pool

Answer 1

A bottleneck event in a population causes a small gene pool, which can lead to reduced genetic diversity and an increased likelihood of harmful genetic mutations. This can also decrease the availability of advantageous traits and limit the ability of the population to adapt to changing environments, which can ultimately lead to a decline in population size or even extinction.
