Mitosis vs Meiosis

 Meiosis

Definitions

• reproduction- the production of offspring by a sexual or asexual process.
• sexual reproduction-the production of new living organisms by combining genetic information from two individuals of different types (sexes). 
• asexual reproduction- reproduction in the absence of a mate.
• mitosis-a process where cell divides, resulting in two identical cells
• meiosis-a specialized form of cell division that ultimately gives rise to non-identical sex cells
• gametes-a reproductive cell
• zygote-A fertilized eukaryotic cell; a cell after the union of male and female gametes
• syngamy=fertilization- The fusion of gametes resulting in the formation of a zygote, which develops into a new organism
