An organism's characteristics are controlled by alleles which occur in pairs, each being located on one of the two homologous chromosomes In meiosis the homologous chromosomes segregate and thus the gametes receive only one of a pair of alleles On
fertilisation there is a recombination of alleles, one from the male parent and one from the female Though it is a matter of pure
chance which two gametes combine, every possible combination is actually produced if there are large enough numbers of
offspring
