Male and Female are the Only Two Genders

Male and Female are the Only Two Genders.
Biological science confirms if a child is conceived with an X+Y combination of genes, he is a boy from the moment of conception and will be a male until the day he dies. If a child is conceived with an X+X combination, she is a girl from the moment of conception and will be a female until the day she dies.
Only two genders is an anatomical, biological, scientific fact.
