Question
Why does sexual reproduction result in greater variation among offspring?
The correct answer is
It allows combination of genetic material from two individuals.
Sexual Reproduction and Genetic Variation
Sexual reproduction introduces greater genetic variation among offspring because it involves the mixing of genetic material from two distinct parents.
- Parental Contribution: Each parent contributes half of the offspring's genetic material through specialized reproductive cells (gametes).
- Recombination: During fertilization, these gametes fuse, combining genes from both parents in a unique arrangement.
- Novel Combinations: This process creates new combinations of alleles, resulting in offspring that differ genetically from each other and from the parents.
This mechanism contrasts with asexual reproduction, where offspring are typically clones of the single parent, showing minimal variation.
