Document Summary
Gametes are cells produced during sexual reproduction which contains a copy of half of that parent"s genetic material. Male gametes are known as spermatozoa, female gametes are known as ova or eggs. They consists of half of the number of chromosomes that most cells of the body have. Most cells of the body are diploid, they contain 2 sets of 23 chromosomes (2n). On the other hand, gametes are haploid as they contain only single set of 23 chromosomes (n). Fertilization is the process in which gametes from a male and female fuse together to produce a new cell. In each haploid cell, they are 23 chromosomes:22 autosomes plus one sex chromosomes. Each chromosome is unique from the other by its shape. Autosomes are the chromosomes other than the sex chromosome. Unlike the sex chromosomes, the autosomes always come in matching pairs. The members of each pair of autosomes are said to be homologous.
