comment How many genes do we share with our mother?
@Michael Kuhn: Sorry, I was really not correct in the end part of my comment. What I should have written is that the X from their mother is a recombination of the two Xs of their mother. There is a small recombinable part in the Y chromosome but it does not contain the key genes for sex determination.

comment Why are (some) cats attracted by bleach?
- (I know we are on biology.SE and not on Pet.SE but) Would a neutered male cat exhibit a change in behavior when crossing the path of a female in oestrus?

comment Why are (some) cats attracted by bleach?
In response to your experience proposal, I can already give partial answers: - I have already exposed this cat to various compound known to cause "catnip" behavior in cats such as catnip and valeriane (the first bought, the second naturally occuring in my garden), and he did not, did not show any interest in it whatsoever while another visiting cat did.

comment How many genes do we share with our mother?
Let's not forget in these explanations about the special case of X and Y genes. If you are a boy, you share 100% of your father's Y chromosome (with a few mutations/transcriptions errors and slight recombinations in between) and a 50% mix of a X chromosome from him and a X chromosome from your mother.
