Question

Which two processes are the primary sources of genetic variation?
mitosis and fertilization
synapsis and disjunction
mutation and recombination
overpopulation and reproduction

Answer 1

Answer:

mutation and recombination

Explanation:

Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
