✔✔Mutation and gene flow - ✔✔In which of the following pairs do both evolutionary
processes introduce new genetic variation into a population?
✔✔True - ✔✔Mutation can be defined as the addition of genetic variation that increases
the hereditary diversity of a population.

✔✔Gene flow - ✔✔When male lions reach sexual maturity, they leave their group in
search of a new pride. This can alter the allele frequencies of the population through
which of the following mechanisms?
✔✔Inbreeding can bring together rare, deleterious mutations that lead to harmful
phenotypes. - ✔✔When closely related individuals mate with each other, or inbreed, the
offspring are often not as fit as the offspring of two unrelated individuals. Why?
