What is another word for sperm and egg cells in meiosis?

Reproductive cells are also called gametes or sex cells. Fertilization occurs when two reproductive cells, or gametes, of the opposite sex unite to form a different and complete organism. Male gametes are called sperm, and female games are called eggs or ova. These cells are created through the process of meiosis, in which a parent cell with two copies of each chromosome goes through DNA replication and nuclear division. The result of these processes is four separate reproductive cells.gamete is either a sperm or an egg. Each gamete has one set of chromosomes that combines with the chromosomes of another gamete to create a new organism.
