Asexual reproduction- reproduction without sex, a single organism replicates itself. Main process of asexual reproduction is mitosis> mostly occurs in single-celled organisms.
Binary Fission- common in prokaryotes, a living cell divides into 2 cells. Always results in daughter cells, offspring identical to parent unless mutation occurs.
Budding- Used by plants and some animals; cannot simply divide into 2. A small part of plant/animal breaks off and then start to grow until it reaches the same size as the parent> capable of budding again.
Sexual reproduction- process of reproduction of some animals/plants. Male/ Female.
Gonads- specialized sex organs where gametes are formed. In the male, the gonad is the testes, while in the female, the gonad is the ovaries.
Diploid Cells- 2n: have two homologous copies of each chromosome, usually one from the mother and one from the father.
Haploid Cells-The haploid number (n) is the number of chromosomes in a gamete.
Gametes-specialized sex cells formed in gonads by gametogenesis. The male gamete is the sperm, and the female is ovum or egg.
Zygote-produced by fertilization between two haploid cells, the ovum and the sperm cells, which make a diploid cell.
Asexual Reproduction- no mate needed; many offspring are the result
Sexual reproduction- genetic variation
