Chromosome pair 1 consists of chromosome A and B, pair 2 of C and D and pair 3 of E and F. In the meiosis the pairs the chromosome pairs split and go by chance to a sperm cell. In this way sperm cells are created with 8 (23) different combinations of chromosomes: ACE, ACF, BCE, BCF, ADE, ADF, BDE and BDF. When a species has n chromosomes the parents create 2n different sperm cells or oocytes.

DefinitionsMeiosis is the process carried out in the germ cells by which gametes are formed. In diploids this involves the creation of haploid cells (sperm, oocytes) from the diploid progenitor cells Mendelian sampling is the random sampling of parental genes caused by segregation and independent assortment of genes during germ cell formation, and by random selection of gametes in the formation of the embryo |
