106 â A CHAPTER 4 Cell Reproduction Sexual Reproduction Another way that a new organism can be produced is by sex-ual reproduction. During sexual reproduction, two sex cells,sometimes called an egg and a sperm, come together. Sex cells,like those in Figure 9, are formed from cells in reproductiveorgans.Sperm are formed in the male reproductive organs. Eggs are formed in the female reproductive organs.The joiningof an egg and a sperm is called fertilization, and the cell thatforms is called a zygote (ZI goht).Generally, the egg and thesperm come from two different organisms of the same species.Following fertilization, mitosis and cell division begins.he joiningof an egg and a sperm is called fertilization, and the cell thatforms is called a zygote (ZI goht). Generally, the egg and thesperm come from two different organisms of the same species.Following fertilization, mitosis and cell division begins.
The process of sexual reproduction involves two parents, each contributing one gamete. Gametes are produced. by a process called meiosis, which starts by the duplication of the chromosomes, followed by two rounds of cell divisions and halving of the chromosome number. Gametes have half the chromosome number of other adult. cells of an organism. A key feature of meiosis is the exchange of chromosome pieces which occurs in the first division of this process, called recombination or crossing over.
