उत्तर
- Sexual reproduction involves two parents i.e. male parent and female parent.
- The male gamete coming from a male parent fuses with a female gamete of a female parent to form a zygote which develops into an embryo and then into a new individual.
Thus, the new individual always has the recombined genes of both the parents.
