Chromosomes and reproduction pairs + an xx or xy pair. Every cell in your body except sperm or oocyte contains 46 chromosomes: 22. Gametes, or reproductive cells (sperm and oocytes) contain only one chromosome of each pair and an x or y chromosome. One chromosome pair may contain dna about blood type, eye colour, widow"s peak or not, info isn"t usually identical. At fertilization, you would have 92 chromosomes. Important to have equal gametes chromosome, each have to have one part of the pair. When gametes form, chromosome pairs separate haploid. At fertilization, haploid sperm and oocyte come together and create 46 chromosomes. Genetically identical twins = cells separate into two groups, finger prints are unique to each person. The gonads the pair of organs that produce reproductive cells are termed gonads. In the male, these are the testes (testicles) that are located outside the body cavity in the scotal sac.
