Study Notes
Gamete and Sexual Reproduction
- A gamete is a specialized cell that fuses with another gamete during sexual reproduction, resulting in the formation of a zygote.
Sexual Reproduction
- Sexual reproduction involves the fusion of two gametes, each contributing half of the genetic material, to form a zygote with a complete set of chromosomes.
- This process increases genetic diversity by combining genetic information from two parents.
Commonality of Sexual Reproduction
- Sexual reproduction is most common in multicellular organisms, such as animals, plants, and fungi.
Result of Gamete Combination
- The result of the combination of gametes in sexual reproduction is a zygote, which develops into a new individual with a unique combination of genetic traits.
Exceptions to Sexual Reproduction
- Sexual reproduction does not occur in single-celled organisms, such as bacteria, which reproduce asexually through binary fission or other mechanisms.
