Which of the following scenarios will decrease the genetic variation of a population? (1 point) O a mutation in a chromosome makes it more likely to undergo genetic recombination
O a population of birds suddenly decrease their frequency of sexual reproduction
O an individual works out, increasing their muscle mass
O a mutation alters the sequence of a gene resulting in a new allele

B

Explanation:

Will less reproduction there is less of a change for mutations and favorable traits and therefore decreases genetic variation
