Remember that all the random possible
combinations of the members of a population
would equal (c x c) + 2cd + (d x d), or (c+d) X
(c+d)
Then, c + d = 0.4 + 0.6 = 1
And (c x c) + 2cd + (d x d)
= BB + Bb + bb
= .24 + .48 + .30 = 1
This means that the population can increase in
size, but the frequencies of B and b will stay
the same.
Now, suppose we break the 4th law about not
introducing another population into this one.
Let us say that we add 4 more b.
b + b + b + b enter the pool. This brings our
total up to 34 instead of 30. What will the
gene and genotypic frequencies be?
