Title: What increases the number of alleles in a species (not just a population)?
Post by: Nonameeee on Dec 16, 2020
1. Natural selection
2. Bottleneck effect
3. Founder effect
4. mutation
5. Gene flow


I'm torn between mutation and natural selection.. .

An entire species or an individual? Hate the way it's written.

If we're talking about Homo sapiens, the species say, what INCREASES the number of alleles is gene flow.

The introduction of new alleles through gene flow increases variability within the population and makes possible new combinations of traits. In humans gene flow usually comes about through the actual migration of human populations, either voluntary or forced.
