which of the following is not related to genetic drift?

neutral variation

sexual selection

non darwinian evolution

bottleneck effect

founder effect

Expert Solution

Answer: Sexual selection

Explanation: Sexual selection is a form of natural selection in which individuals with certain traits are more likely to obtain a mating partner.

- Genetic drift is a random process in which the allelic frequency changes and genetic diversity reduces in a population.

- This results in genetic variation. Sexual selection is a form a natural selection. So, it is a nonrandom process and due to it the genetic variation increases.

- Hence, it does not contribute to genetic drift.

Other Options:

- Neutral variation is a genetic variation that shows no selective advantage. Hence, it contributes to genetic drift and not natural selection.

- Non-Darwinian evolution shows that apart from natural selection factors like genetic drift, mutation and migration also plays role in the course of evolution.

- Founder effect: it is also a reduction in the genetic diversity in a population that is descended from a small number of ancestors. It contributes to genetic drift.

- Bottleneck effect is also a sharp reduction in a population due to earthquakes, flood, genocides or droughts. This also contributes to genetic drift.

Sexual selection on traits involved in mate choice can lead to complex patterns of genetic variation...

Sexual selection on traits involved in mate choice can lead to complex patterns of genetic variation in populations. The African Great Lakes contain a stunning diversity of cichlid fish species, which have recently evolved due to a combination of ecological adaption and sexual selection. In one recently evolved species, we observe the following pattern: An autosomal (not sex linked) locus “X” involved in pigmentation has different effects in male fish than female fish. There are two alleles in this system....
