Sexual Reproduction

Question

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

Easy

A

sexual reproduction is a lengthy process
B

gametes of parents have qualitatively different genetic composition
C

genetic material comes from parents of two different species
D

greater amount of DNA is involved in sexual reproduction

Solution

In sexual reproduction genetic variation is observed. In this mode of reproduction, gametes of two parents (opposite sex) having qualitatively different genetic composition participate in the reproductive process, (i.e. fusion of male and female gametes). This gives rise to a new individual having an entirely new genetic makeup.
