Human cells have 46 chromosomes that are placed into 23 pairs, with one chromosome of each pair coming from the father and mother separately. Discover what an extra or missing chromosome causes with information from a science teacher in this free video on physiology and the human body.

AWESOME VIDEO!
thanks a ton(:
*finished Bio homework*

[jyothi]

is these chromosomes are in every cell? is it so aneuploidy is in every cell!!but how can it happen!!!

[nicnac]

I know all this advanced stuff but forget the small stuff thanksss

[nightbot.]

o yeah!? so why does pink guy have over 9000 chromosomes

Even though Doom was a movie it said 23 chromosomes was that 23 pair of chromosomes and 24 pair of chromosomes make fictional creatures superhuman so individually there are 46 or over 1 quadrillion like that person above said in a comment said

"One of this Cromosone is come from your mother"- Is this wrong? shouldn't Janice say one of the DNA helix?
thanx

Im having hell trying to figure this stuff out.
are there like 11 x chromosomes and 11 y chromosomes and a wild card chromosome?
What order do they go in?
xyxyxyxyxyxyxyxyxyxyxyx?
xxyyxxyyxxyyxxyyxxyyxxy?
Anything like that?

Every somatic ell has 46 chromosomes or pair of 23 chromosomes so how many somatic cell?
Here, there are 37.2 trillion numbers of somatic cell so if 46 are present in each then
Finally (46×37.2) trillion
So there are 1.7112 quadrillion chromosomes in a normal human body.
