Hardy-Weinberg Equilibrium Part 2

If we mate two individuals that are

heterozygous (e.g., Bb) for a trait what will

we find? (Let’s make the punnet square).

Look at that. In this group our resulting

offspring will be:

1 BB,

2 Bb,

1 bb

This means that:

25% of their offspring are homozygous for the

dominant allele (BB).

50% are heterozygous like their parents (Bb)

and

25% are homozygous for the recessive allele

(bb).

Now look at this closely. Unlike their

parents Bb Bb, 25% will express the recessive

(^) B b
