what is genetic deaft
Answers
Answer:
Genetic drift is the change in the frequency of an existing gene variant in a population due to random sampling of organisms. The alleles in the offspring are a sample of those in the parents, and chance has a role in determining whether a given individual survives and reproduces.

Explanation:
variation in the relative frequency of different genotypes in a small population, owing to the chance disappearance of particular genes as individuals die or do not reproduce. this is meaning of this word.

this is Importance of this question
So, genetic drift could be important in determining whether a new mutation is lost, or whether it instead becomes common enough for selection to determine its fate. In theory, in a small enough population genetic drift could also be important even for common alleles.
