Gametogenesis


Gametogenesis is a process of formation of gametes – reproduction cells. The gametes are created in special type of the cell division called meiosis. During meiosis the diploid parent cell divides into haploid daughter cells. Haploid cell has just one set of chromosomes (23 pairs). The fetus is created by fusion of two haploid cells – a womans egg and mans sperm. Each cell of fetus is then diploid – it contains 46 chromosomes. Children have one set of chromosomes from each parent. But information which is transferred is not always the same. That is the reason why siblings don´t look like each other or like their parents. Gametogenesis is extremely variable process.
