Answer:
The correct answer would be B. Sexual reproduction increases genetic diversity.
The main advantage of the sexual reproduction over the asexual reproduction is that it increases genetic diversity in the population.
It is achieved in two ways:
Genetic makeup the offspring is made by the combination of both the parental and maternal genome. Half of the chromosomes of the offspring are provided by the mother's egg and other half are provided by parental's sperm.
In addition, a unique event of crossing-over also takes place during the formation of gametes which also adds up to the genetic variation of the population.
Exchange of genetic material between non-sister chromatids of homologous chromosomes takes place in crossing-over which results in the formation of a new combination of alleles in chromosomes.
It leads to the development of genetic diversity in sexually reproducing organisms.
