Asexual reproduction

Definition

Asexual reproduction is a mode of reproduction in which offspring are produced by a single parent without the involvement of gamete fusion. This process results in genetically identical offspring, or clones, of the parent organism.

5 Must Know Facts For Your Next Test

1. Asexual reproduction in prokaryotes primarily occurs through binary fission.
2. Despite genetic uniformity, prokaryotes achieve genetic diversity through mechanisms such as mutation, transformation, transduction, and conjugation.
3. Binary fission involves the replication of the bacterial chromosome and division of the cell into two genetically identical daughter cells.
4. Horizontal gene transfer allows for the introduction of new genetic material from other organisms, contributing to genetic variation.
5. Mutation rates in prokaryotes are relatively high due to their short generation times and large population sizes.

Mutation: A change in the DNA sequence that can introduce genetic variation within an organism's genome.
