Crossing over
C
Mutations
D
Asexual reproduction
Explanation: 

Detailed explanation-1: -Disadvantages of asexual reproduction It does not lead to genetic variation in a population.

Detailed explanation-2: -Asexual species, on the other hand, do not have genetic variability like we do-each of their offspring has the exact same genetic makeup as their parent.

Detailed explanation-3: -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).
