Question

1. in your own words, explain how geography influences genetics. rbio africa storyline

Explanation:

Geography can create physical barriers like mountains or oceans that limit gene - flow between populations, leading to genetic differences. Geographic factors such as climate can also exert selective pressures. For example, in areas with high levels of sunlight, genes related to skin pigmentation may be selected for to protect against UV radiation. Migration patterns influenced by geography can introduce new genes into populations, altering their genetic makeup.

Answer:

Geography creates barriers limiting gene - flow, exerts selective pressures based on climate, and influences migration patterns that change genetic makeup.
