Question

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

• A. Genetic material comes from parents of two different species
• B. Greater amount of DNA is involved in sexual reproduction
• C. Gametes of parents have qualitatively different genetic composition
• D. Sexual reproduction is a lengthy process

Answer 1

The correct option is C Gametes of parents have qualitatively different genetic composition

Genetic composition of gametes:

Gamete formation, a key event in sexual reproduction, happens usually through meiotic division where crossing over leads to changes in genetic makeup of the gametes. This leads to genetic recombination. The genetic composition of the gametes thus formed differs compared to the parent cells.

Fusion of male and female gametes results in the formation of a zygote containing genetic material not exactly identical to either of the parents due to different genetic composition of the gametes.




Final answer:

b. Gametes of parents have qualitatively different genetic composition
