If you make a Punnett square with Aa and Aa, you'll see that the ratios are:
AA:Aa:aa=1:2:1
so the ratio of aa out of the total is 1/(1+2+1)=1/4
B-16
Explanation:
Basically, a germ cell (sperm or egg cell) is
n
. Now, the stomach cell, which is a somatic cell, is 2n
.
If you substitute
2(8)=16
Germ cells have gametes while somatic cells have chromosomes.
