I could be wrong I haven't checked, but women have 2 x's and men have an x and a y. So is an x more DNA than a y?

I was starting with the premise that 4 legs is 1/3 more than 3 legs... but 3 times? Wow. Is that geometrically justified?phyzguy said:Yes. The X chromosome has about 3 times the number of base pairs as the Y.

False, the second X chromesone is turned off.Drakkith said:The Y chromosome is not Y-shaped, nor is a single copy of the X chromosome X-shaped. Below you can see an XY pair of a human male. You'll notice that the X chromosome is must larger than the Y chromosome. Note that if we count the X chromosome as being three 'units' in size and the Y as being one unit, an XX pair is 6 units in size while an XY pair is 4 units (~312 Mbp vs ~213 Mbp). So women have roughly 100 million more base-pairs than men.

Ygggdrasil said:Note that in female human cells, the cells essentially crumple up and ignore one copy of their X-chromosomes, and only use one copy of their two X-chromosomes, so that extra DNA does not have major effects on cells aside from specifying the sex of the individual.
I never mentioned anything about active or inactive base pairs.okmj4ongokrwe said:False, the second X chromesone is turned off.

yes, calico/tortoiseshell cats are classic oft-quoted examples of genetic mosaicism. Lots of explanations online. Whether you get large patches as with tortoiseshell or something more finely distributed will, it is not hard to surmise, depend what stage, what number of cells of the particular somatic line that gives rise to the definitive tissue, the inactivation process kicks in.JT Smith said:I foster kittens as a kind of hobby and it's the reason I've read for the color distribution in certain female cats (e.g. Calico).
So in terms of genetic material women DO have more BUT in terms of every X chromosome, 50% are inactive.Drakkith said:I never mentioned anything about active or inactive base pairs.
Yes, women and men have the same amount of DNA, but women have two X chromosomes while men have one X and one Y chromosome. This means that women have more DNA overall, but the amount is the same in each individual cell.
Women have two X chromosomes because they inherit one X chromosome from each parent. Men, on the other hand, inherit one X chromosome from their mother and one Y chromosome from their father.
No, the amount of DNA does not determine intelligence. While women may have more DNA, it does not mean they are smarter than men. Intelligence is influenced by a variety of factors, including genetics, environment, and education.
The X and Y chromosomes determine biological sex, with the X chromosome carrying genes related to female characteristics and the Y chromosome carrying genes related to male characteristics. The X chromosome is larger and contains more genetic information than the Y chromosome.
Yes, some individuals can have more than two X chromosomes. This is known as Triple X syndrome or Trisomy X and occurs in about 1 in 1,000 females. It can lead to physical and developmental differences, but does not necessarily affect intelligence or personality.
