Are the bottleneck effect and the founder effect the only ways in which genetic drift can occur?

We learned something called genetic drift. It's a process in which random events can make certain genes just drift away and then automatically, the genes that survive that random event will get more …

Natural selection can act on traits determined by different alleles of a single gene, or on polygenic traits (traits determined by many genes). Polygenic traits in a population often form a bell curve distribution.

Genetic Drift: Genetic drift is the random fluctuation of allele frequencies in a population due to chance events. It is especially significant in small populations, where the effects of random sampling of …

The population will not only evolve (change in its genetic makeup and inherited traits), but will evolve in such a way that it becomes adapted, or better-suited, to its environment.

One advantage to choosing cross-breeds and mixed-breeds over purebred dogs is that harmful genetic mutations that tend to frequently occur in certain lineages can be covered up, or “bred out”, by the …
