One DNA molecule per cell

Replicate to two DNAs.

Now segregate to two daughter cells

If totally random, half of the cells will have too many or too few.

What about human cells with 46 chromosomes (DNA molecules)?

Exactly 46 chromosomes (but any 46):

B(X) = C(n,x) px qn-x

n=46*2; x=46; p=0.5

B(X)= 0.083

P(X) = mx e-m/ X!

m=X=np=46, P(X)=0.058

But what about exactly

the correct 46?

0.546 = 1.4 x 10-14

Might this select for non random segregation?
