What is "x chromosomes"

Usage examples of "x chromosomes".

One in 500 Gliksin children were born with a sex-chromosome difficulty, such as Klinefelter syndrome (two or more X chromosomes and a Y, or often a mosaic), triple-X syndrome, Turner syndrome (a single X chromosome either completely lacking a mate or with a truncated second sex chromosome), or XYY syndrome, which could predispose males to violence—.

Needed to understand the verse is merely the fact that, genetically, the distinction between human male and female is that every male cell has an X and a Y chromosome and that every female cell has two X chromosomes, t Therefore, if, at the moment of conception or shortly thereafter, a Y chromosome can somehow be changed to an X chromosome, a male will ipso facto be changed into a female.

In fact, though, people abnormally endowed with one Y and two X chromosomes turn out most like males, whereas people endowed with three or just one X chromosome turn out most like females.

Y chromosomes in humans lacked these passages, and they also matched with chimpanzees more completely than X chromosomes did.

As nearly as we can tell, only those women who have received the trait on both their X chromosomes ever actually develop the disease.

We took the less dominant of the two X chromosomes in your body, retained what would be common to X and Y, added the Y instruction set that was not present before, and threw out most of the rest of the X chromosome since the Y is such a wimp, you might say, compared to the X.

And there was that one excruciating conversation with Dad in the garage helping him mix the paint for the wood trim around the doors and windows, when Dad's weird questions finally coalesced enough for Quentin to blush furiously and reassure him that yes, Quentin liked girls and not boys, he simply hadn't found the right girl yet but he was looking and don't worry, Dad, when I do bring somebody home she'll wear a dress and she'll have two X chromosomes, now can we please just paint the trim?
