Difference Between Genetic Drift and Gene Flow

WebSince there are only two alleles in the gene pool, it is possible to compute the frequency of the recessive allele by subtracting the frequency of the dominant allele from 1. The frequency of the recessive gene in this situation would be 1 - 0.35 = 0.65. 2. WebJan 15, 2024 · Genetic Drift vs. Gene Flow.

WebSep 4, 2024 · Genetic Drift. Genetic drift is a random change in allele frequencies that occurs in a small population. When a small number of parents produce just a few … WebGenetic drift occurs because the alleles in an offspring generation are a random sample of the alleles in the parent generation. Alleles may or may not make it into the next generation due to chance events including mortality of an individual, events affecting finding a mate, and even the events affecting which gametes end up in fertilizations.
