Question

why is genetic variation important for the survival of a population? it guarantees that all individuals survive it allows populations to adapt to environmental changes it prevents mutations from occurring it increases the size of the population

Explanation:

Genetic variation creates a range of traits in a population. When environmental conditions change, some individuals with favorable traits will survive and reproduce, allowing the population to adapt. Genetic variation does not guarantee all individuals survive, does not prevent mutations, and does not directly increase population size.

Answer:

It allows populations to adapt to environmental changes
