Now, these right here are called homologous chromosomes.

This is Human vs. Chimps the few chromosomes that distinguish us from chimps.

This is what you look like. This is one of your chromosomes.

You see here the work of Ben Fry. This is Human vs. Chimps the few chromosomes that distinguish us from chimps.

Males with Klinefelter syndrome typically have one extra copy of the X chromosome in each cell, for a total of two X chromosomes and one Y chromosome (47,XXY).

So we're now making several dozen different constructs, because we can vary the cassettes and the genes that go into this artificial chromosome.

Other disorders XX male syndrome is a rare disorder, where the SRY region of the Y chromosome has recombined to be located on one of the X chromosomes.

Now in the nature area, we look at whether or not we are innately equipped with something, perhaps in our brains, some abnormal chromosome that causes this muse like effect.

Early in embryonic development in females, one of the two X chromosomes is randomly and permanently inactivated in nearly all somatic cells (cells other than egg and sperm cells).

When additional X and or Y chromosomes are present in 48,XXXY, 48,XXYY, or 49,XXXXY, developmental delays and cognitive difficulties can be more severe and mild intellectual disability may be present.
