• Vanhurume vane 1 X uye 1 Y chromosome.

Amai vanopa X chromosome kumwana. Ivo baba vanogona kupa X kana Y. Iyo chromosome kubva kuna baba inoona kana mwana akazvarwa ari murume kana mukadzi.

Iwo akasara echromosomes anonzi autosomal chromosomes. Ivo vanozivikanwa semakromosomes maviri 1 kusvika 22.
