The Punnett square is a diagram that is used to predict an outcome of a particular
cross or breeding experiment. It is named after Reginald C. Punnett, who devised
the approach. The diagram is used ...

genotypic ratio. The expected numbers of different genotypes produced by a
particular cross. Example: 1 RR, 2 Rr, and 1 rr individuals could result from a
A Punnett Square shows the genotypes two individuals can produce when
crossed. To draw ... The phenotype ratio predicted for dihybrid cross is 9:3:3:1. Of
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
Because each possibility is equally likely, genotypic ratios can be determined
from a Punnett square. If the pattern of inheritance (dominant or recessive) is ...
