Detailed explanation-1: -Sexual reproduction has the potential to produce tremendous genetic variation in offspring. This variation is due to independent assortment and crossing-over during meiosis, and random union of gametes during fertilization.
Detailed explanation-2: -Sexual reproduction has the advantage of increasing genetic variation in offspring. Asexual reproduction has the advantage of producing offspring rapidly, especially in the case of bacteria.
Detailed explanation-3: -The advantages of sexual reproduction: it produces variation in the offspring. the species can adapt to new environments due to variation, which gives them a survival advantage. a disease is less likely to affect all the individuals in a population.
Detailed explanation-4: -it does not lead to variation in a population. the species may only be suited to one habitat.
Detailed explanation-5: -The process of sexual reproduction introduces variation into the species because the alleles that the mother and the father carry are mixed together in the offspring.
