Offspring formed by sexual reproduction ...

Offspring formed by sexual reproduction exhibit more variation than those formed by Asexual reproduction because.
(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.

Sexual reproduction is a lengthy process.

Gametes of parents have qualitatively different genetic composition.

Genetic material comes from parents of two different species.

Greater amount of DNA is involved in sexual reproduction.

Text Solution

Verified by Experts

The correct Answer is:

Offspring formed by sexual reproduction exhibit more variation than those formed by asexual reproduction because gametes of parents have qualitatively different genetic composition (due to crossing over).
In asexual reproduction only one parent is involved, so there is no chance of variation.
