Haploid Gametes

•  Gametes are haploid so contain only one allele of each gene

•  The two alleles of each gene separate into different haploid nuclei during meiosis

Gametes are haploid sex cells formed by the process of meiosis – males produce sperm and females produce ova

  • During meiosis I, homologous chromosomes are separated into different nuclei prior to cell division
  • As homologous chromosomes carry the same genes, segregation of the chromosomes also separates the allele pairs
  • Consequently, as gametes contain only one copy of each chromosome they therefore carry only one allele of each gene
