Study Notes

Characteristics of Sexual Reproduction

The defining characteristic of sexual reproduction is the fusion of gametes from two parents to form a zygote with a unique combination of genes.

Organisms and Sexual Reproduction

Sexual reproduction most commonly occurs in multicellular organisms, such as plants and animals.
Organisms that do not undergo sexual reproduction include some single-celled organisms, such as bacteria, and some plants that reproduce vegetatively.

Gametes in Sexual Reproduction

Gametes are specialized cells, such as sperm and egg cells, that fuse to form a zygote during sexual reproduction.
The role of gametes is to provide genetic material from each parent for the offspring.

Sexual Reproduction in Unicellular Eukaryotes

In some unicellular eukaryotes, such as protozoa, sexual reproduction serves as a means of increasing genetic diversity, promoting adaptation to changing environments, and improving the ability to survive and reproduce.
