The correct answer is option B, that is, Genetic drift greatly affects small populations, but large populations can recover.
Genetic drift in combination with mutation, natural selection, and migration is one of the most fundamental mechanisms of evolution. Genetic drift refers to a change in the relative frequency of distinct genotypes in a small populace, owing to the chance vanishing of specific genes as individuals do not reproduce or die.
Genetics affects speciation mostly via mutation caused due to adaptation and environmental conditions.
Explanation:
- The Speciation is defined as the evolution of a species into a distinct species. The cause of this could be several, and some of them could be environmental conditions, mutations, etc
- Environmental conditions include isolation of the species caused by mountain rise, river, flood etc. to survive they have to evolve or get adaptations to living in those conditions
- Mutation happens for many reasons, external factors can also cause the mutations to occur. It will also lead to speciation.
