Amouse 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

Option C: Gene flow

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:

so whats the answer

he forelimbs below belong to four species that descended in a direct line from the ancestral mammal shown above. of the four descendants shown, which species most likely appeared earliest in evolutionary history?
