Options
(a) Mutations only

(c) Mutations as well as recombination
(d) Reproductive isolation and selection
Correct Answer:
Mutations as well as recombination

Crossing over leads to recombination of gentic material on the two chromosomes. Mutation results in alternation of DNA sequences and consequently results in change in the genotype and the phenotype of an organism. In addition to recombination, mutation is another phenomenon that leads to variation in DNA.
