Question

genes that are needed in both males and females cannot be located on the (x or y ) chromosome ?

Answer 1

No, the x and y chromosome are the make up of the human's DNA, with out both of them, you wouldn't live. The more x chromosome based genes you have, your a boy, but, if you have more y chromosome based genes, your a girl. Everything that related to things that are needed are found in the x and y chromosomes, they make you who you are.

If i didn't have the red hair chromosome from my mum, i wouldn't be a red-head. If my dad didn't pass down the height in his x chromosomes, i wouldn't be tall. everything that makes you, you, is found in the X and Y chromosomes from the two parents.
