Sexual reproduction

Definition

Sexual reproduction involves the combination of genetic material from two parent organisms to create offspring with genetic diversity. This process typically includes meiosis and fertilization.

5 Must Know Facts For Your Next Test

1. Sexual reproduction increases genetic diversity, which is crucial for evolution and adaptation.
2. Meiosis is a key part of sexual reproduction, resulting in haploid cells that combine during fertilization.
3. In microbes, sexual reproduction can involve processes like conjugation, transformation, and transduction.
4. Unlike asexual reproduction, sexual reproduction requires two parent organisms or cells.
5. Genetic recombination during sexual reproduction can introduce new traits and improve survival in changing environments.
