Web21 Jul 2024 · An exception to this rule are the sex cells (egg and sperm), also known as gametes, which only have one set of chromosomes each (they are haploid). However, in sexual reproduction the sperm cell combines with the egg cell to form the first cell of the new organism in a process called fertilisation. WebInstead, sex cells (sperm and eggs) have only half the number of chromosomes of a non-sex (or autosomal), cell. To achieve half the number of chromosomes, the germ cells (the cells that form sperm and eggs) undergo a process called meiosis. In human meiosis, each of the resulting cells has only one of each of your 23 chromosome pairs instead of ...
