Because each possibility is equally likely, genotypic ratios can be determined
from a Punnett square. If the pattern of inheritance (dominant or recessive) is ...
This conclusion is often expressed as a genotypic ratio: 1 BB:2Bb:1bb. This
means that we are predicting that, for every BB baby, they should have 2 Bb
