that is/you are so fucking retarded i dont even know where to begin.

to be classified as a female, you must possess the female reproductive organs.

youre essentially saying that humans start of possessing female reproductive organs and then about half of them have their reproductive organs mysteriously vanish to be replaced by cocks.

Whoa. Lrn2 biology you inept cunt.

The SPERM determines the gender of the child.

After Meiosis II, the female gamete will always contain an X chromosome, but the male gamete may contain either an X or a Y chromosome, this is because the male DNA contains both types, and so during cell division splits up the XY into one X sperm and one Y sperm.

DNA does NOT send any specific signal, chemical or otherwise to determine which sperm penetrates your stupid cunt egg, wheter it contain X or Y chromosome.

I dont have to because they arent you fucking idiot.

Until the testes are formed, the baby is physiologically ASEXUAL, however that itself is inaccurate as on a molecular level, the baby is MALE the moment it can be classified as a baby and even the moment a sperm containing a Y chromosome intermingles with the X chromosome in the egg. Its blastocyst and stem cells upon analysis at a molecular level will TELL YOU THAT THE BABY IS MALE.

I cant help if youre a stupid cunt that believes that a baby is female until a dick appears.

No one fully knows how gender is genetically determined. But we know what role a few genes play in this.

This female default conception is old dogma. There is some truth to it, but it doesn't really do justice to the complexity of sex determination. There are separate paths by which genes determine sex and they are both triggered actively, so there isn't really a default.

Never did I say that I was actually serious little boy. Googling, and not looking at YahooAnswers, provides information stating that while babies begin looking feminine, they haven't developed testes or ovaries and therefore do not have female repoductive organs. Also whether or not it is going to a boy or a girl is decided by the sperm and once conception happens, this will not change (barring the small percentage).

But again, I will say this: It was very amusing to watch you get your panties in a twist little boy.

I know you're trolling, but I'll bite...
There are males born without the Y chromosome, so sex determination is much more complex than that. There are genes which promote the male or female sex and genes which suppress the formation of a certain sex. So, it's more of a struggle between a number of genes to push the development in one direction or another.

Random assortment has everything to do with it you moron.

L2fuckingbiology

A male's cell will initially start off containing both X and Y chromosomes. At the start of meiosis I, your cell will be a diploid containing both X and Y still but by the end of meiosis II, a single haploid gamete will only contain either X or Y. In other words, each sperm in the male body either contains an X chromosome or a Y chromosome.

If an X chromosome fertilises the egg, the baby will be female, if a Y chromosome etc etc

Random assortment takes place during both meiosis I and II which sorts out which sperm is laden with which genes including the chromosomes X and Y.

This process is random. Assortment of genes (including X and Y) takes place.

The assortment of genes is random.

The assortment of X and Y is random.

Your sex is determined randomly.

We KNOW that sex is determined randomly and we KNOW why it is random (insofar as we know that a coinflip is random)

Nigger dont get high off nothing.

Wikipedia is as wikipedia is.

In biology, by definition of lacking a Y chromosome, an "XX male" is not male.

Heres a quote from your sauce:

>XX males have two X chromosomes, with one of them containing genetic material from the Y chromosome, making them phenotypically male; they are genetically female but otherwise appear to be male.

A phenotype is merely the physical appearance of an organism that allows taxonomists to easily classify organisms in some levels of the phylogeny and all a phenotype is worth to a geneticist is merely some indication to the alleles being expressed to result in the phenotype.

Let me reiterate this from your link to be clear:

>they are genetically female but otherwise appear to be male.

Nice try though, at least your misconception is a valid one.
