Question

A mouse with curled whiskers migrates from one forest community to another. She mates with other mice in the new community and passes the gene for curled whiskers to her offspring. This is an example of _____.

genetic drift
mutation
gene flow
natural selection

Answer 1

Gene Flow

Step-by-step explanation:

Gene flow is the transfer of genetic variation from one population to another. It is the movement of genes from one population to another population. If the rate of gene flow is high enough, then two populations are considered to have equivalent allele frequencies.

Sometimes gene pools within populations can change because individuals leave that population or new individuals come in. Like water flowing in a river, genes can also 'flow' from one place to another.

For Example:

• A honey bee carrying pollen from one flower population to another.
• A caribou from one herd mating with members of another herd
• A blonde haired, blue-eyed family from Sweden moves to some Asian country where the children grow up, marry and produce offspring who now have the blonde-haired, blue-eyed alleles.
