Q.12 Offspring formed by sexual reproduction exhibit more variation than those formed by asexual reproduction because

(1) sexual reproduction is a lengthy process

(2) gametes of parents have qualitatively different genetic composition

(3) genetic material comes from parents of two different species

(4) greater amount of DNA is involved in sexual reproduction

(c)
Asexual reproduction (budding) has been found in most primitive animals like Hydra, but over the evolutionary time as the higher or advanced organisms came into existence, they resorted the sexual reproduction as it ensures the genetic recombination that results in variation.
