Which is the transfer of genes from one population to another?
gene flow
genetic drift
gene mutation
genetic selection

Answer : The correct answer is-

gene flow.

Gene flow can be described as the process of migration /transfer of variants of gene (also called allele) from one population to another population.

It occurs through interbreeding of organisms between the population.

It can increase the genetic diversity of a population if the allele migrated does not exist previously in that population.

Thus, gene flow is the right answer.

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]
