XX = female Xy=male

so but this logic a man is just a mutated woman, and if you don't belive it then why do men have nipples?

It's actually true. Female DNA is on the whole much more stable than male DNA. Eventually, were natural evolution allowed to progress, we would return to being genderless.

Men have nipples because in the womb, the body develops into a female until a month or something when the Y genes become expressed.

This is actually relevant

men are evolved women

Your mom's relevant.

True statement.  The default in fetal development in the womb is maturation of female characteristics; however, genes on the y chromosome express signaling molecules and what not that suppress some female things and express some males things (example being Testosterone in males causing stimulation and growth of the wolffian ducts which eventually mature into everything from testes to prostate, whereas in females, w/o testosterone that system withers away).

tl;dr
>>5 is correct

Men are really just missing a part of their original X chromosome. 
Women are the standard of perfection.

Suck that, fundamentalist <insert patriarchal religion here>!

Either that or men are more evolved. And go back to the kitchen already.

Love the W gene.

A mutation is an alteration in genes.

Female gametes (ovum) only contain the female X chromosone.
Male gametes (sperm cells) contain either the male and female chromosone (XY) or both female chromosones (XX).
Thus whether the offspring is male or female is decided during the creation of XY or XX chromosones in sperm cells.

During the creation of XY sperm cells no alterations are needed. During the creation of XX sperm cells the Y chromosone must be replaced by a replicated X chromosone. This is a mutation in the loosest definition of the word.

The term mutant is clinical not derogatory, every organism on the planet is a mutant since mutations are essential for evolution. Anyone who associates mutants with deformed monsters and takes it seriously is an idiot.

Chromosones consist of 2 chromatids.

>>20
Irrelevant, since X is one chromosome, not one chromatid. So is Y.

>>21
X is one chromosome, therefore X is 2 chromatids.

>>22
That's what I said, yes.

>>23
So X is 2 chromatids because one chromosome has 2 chromatids, and X is one chromosome.

An additional Y chromosome is way cooler than a stupid redundant X chromosome.

>>24
That's what I said, yes.

XX = Female
XY = Male

What we determine from this is that the Y gene is the dominant sexual characteristic and thus male humans must be the superior gender.

That actually made me wince. Thanks.
