Question

The original sources of variation coming from . can cause gene frequencies to change in a if the immigrants have gene frequencies compared to the host . Then by genetic that enhance reproduction become and remain more common in successive of a . Under certain conditions, that at one time could may lose that capability, thus their adaptations into particular niches. If continues, it may result in the appearance of new species.

Answer 1

The ultimate source of reproduction is mutation.

(Mutation is the only source to bring variation in genotypic frequencies in a population)

What causes gene frequencies to change in a population if the immigrants have different gene frequencies as against to the host population is called Migration.
