If having long fur helps a guinea pig survive, what would you expect to see change in the population as it evolves?

If long fur increases survival, natural selection will favor guinea pigs with the genes for long fur. Over generations you would expect:

- An increase in the frequency of alleles that produce long fur.
- A higher proportion of individuals in the population with long fur (the population mean fur length shifts upward = directional selection).
- If selection is strong and sustained, those alleles may become common or even fixed, and genetic variation for fur length at the relevant loci may decrease.

This outcome requires that fur length is heritable and that long-furred individuals also reproduce more (not just survive).
