Selection and Speciation

Stabilising selection reduce genetic variation by allowing only intermediate phenotype adapted to the environment, and eliminate both of extreme phenotype.

• True

• False

Outbreeding increasing genetic variation by producing hybrid offspring which a result of mating between different species

• True

• False

A robust individual which is adapted to the environment is a product of artificial selection.

• True

• False

Inbreeding decreases genetic variation because the parents of the inbred are closely related.

• True

• False

Moths that cannot camouflage and blend in with the environment have high chances to be eliminated by environment.

• True

• False

Gene flow between different populations increases genetic variation and can lead to a speciation.

• True

• False

Genetic drift decreases genetic variation because a random event in a small population will change the allele frequencies.

• True

• False

Bottleneck effect and founder effect change the allele frequencies by resulting certain allele to be overrepresented or eliminated in the future population

• True

• False

A species is a group of individuals that live in the same area, which can interbreed among themselves and produce fertile offspring.
