Why can't 2 white people produce a dark skinned child with a lot of melanin but 2 black people can create a fair skinned white baby at birth?
Can you explain to me why two white people can't produce a dark-skinned child with a lot of melanin, but two black people can create a fair-skinned white baby at birth?
This has to do with the genes that determine skin color. Melanin is produced by cells called melanocytes, which are regulated by multiple genes. Each person has two copies of each gene - one inherited from their mother and one from their father. When two people with lighter skin tone have a child, the child may inherit two copies of the genes that produce light skin color, which means they will have light skin themselves.
