Study Notes
Sexual Reproduction
- Sexual reproduction is most common in multicellular organisms, particularly in eukaryotes such as animals, plants, and fungi.
Gametes
- A gamete is a reproductive cell, such as a sperm or egg, that fuses with another gamete during sexual reproduction to form a zygote.
Combination of Gametes
- The result of the combination of two gametes in sexual reproduction is a zygote, which is a single cell that contains genetic material from both parents.
Defining Characteristic of Sexual Reproduction in Eukaryotes
- The defining characteristic of sexual reproduction in eukaryotes is the process of meiosis, which involves the reduction of the number of chromosomes by half, resulting in genetically unique gametes.
Organisms that Do Not Undergo Sexual Reproduction
- Prokaryotes, such as bacteria, do not undergo sexual reproduction, instead, they reproduce asexually through binary fission or fragmentation.
