Human cells contain 23 pairs of chromosomes for a total of 46. There are 22 pairs of autosomes and one pair of sex chromosomes. Chromosomes determine everything from hair color and eye color to gender. Whether you are a male or female depends on the presence or absence of certain chromosomes.The sex chromosomes are the X chromosome and the Y chromosome. These chromosomes determine gender.

In human sexual reproduction, two distinct gametes fuse to form a zygote. The male gametes or sperm cells in humans and other mammals are heterogametic and contain one of two types of sex chromosomes. They are either X or Y. The female gametes or eggs however, contain only the X sex chromosome and are homogametic. The sperm cell determines the sex of an individual in this case.

If a sperm cell containing an X chromosome fertilizes an egg, the resulting zygote will be XX or female. If the sperm cell contains a Y chromosome, then the resulting zygote will be XY or male.
Professor:...being the actual meiotic step in which a diploid cell is converted to a haploid cell. This leads us to syngamy where the two gametes form a zygote. Now remember that the combination of two X chromosomes gives us a female and XY chromosomses a male...

Stifler: What the fuck is he on about?

Danny: Shush! The fusion of gametophytes during syngamy, you retard.

Stifler: Professor? Last time we checked Danny's karyotype we came to the shocking discovery that he carries two X chromosomes. Does that make him a female?

Danny: for God sake.

Professor: Perhaps so Mr.Raffaelli, which would explain the somewhat stiff bulge you get each time Mr.Cohen sits next to you.

Danny: Oh my GOD dude! You're homogametic!

n. A member of the human race who is anatomically defined as male and cannot be further classified as either boys (due to their maturing apperience) or men (due to their forever immaturing method of thinking), and are therefore referred to as an "XY", the genetic markup of the pair of sex chromosomes that are normally used to identify the male gender in humans and most other mammals.

XYs by nature are kind and affectionate, but are a socially inept species, and are often caught saying and/or doing the wrong thing at the worst possible time, often oblivious to the inappropriateness of their actions (i.e., obviously admiring the appearance of a good-looking woman while their girlfriend is sitting beside them, and looking puzzled as the aformentioned girlfriend proceeds to knock their teeth out afterwards).

XYs are known to band together in pairs, and despite their lack of social skills, often form long-lasting friendships with one another. However, this triggers a slight to moderate tendency to behave in a fruity manner, frequently causing a majority of XYs to be mistaken as gay.
Fade: Girl, you won't BELIEVE what Ronja did today!

Raven: There's a good chance I probably will, but humor me. What'd he do?

Fade: ...Well, there we were, in his room alone, and things were starting to get...interesting.

Raven: Oh, jeez. It couldn't have gotten THAT interesting,
Fade. The kid has the attention span of a housefly.

Fade: No, no, really. Things were getting hot and heavy in there. We moved rather quickly.

Raven: ...Oh? So he actually had himself together today...? This is new.
Fade: Well, he DID. And then, right as things were hitting a climax--
Raven: Bad way to phrase it.

Fade: --he looked deep into my eyes and called me by his ex's name!

Raven: ...He did what?

Fade: Yep. And when I raised an eyebrow at the mistake, he said it again, without any clue as to what he was doing wrong.

Raven: He's a real genius, that guy.

Fade: And then he had the NERVE to ask me why I was throwing my clothes back on! I mean, he was obviously thinking about HER!

Raven: You seem quite shocked at his stupidity, Fade.

Fade: Aren't you?

Raven: He's an XY. I know not to expect anything better.
