Biology - Mendel's second law table

Mendel's second law table

Complete the table below to predict the chance of various combinations of
alleles. [1] Some have been done for you. The Punnett square method is
easier to use than the algebraic method once you have worked out the
different combination of alleles produced in the gametes. [2]

Predict the dihybrid [3] ratio (9:3:3:1), remembering large numbers of
offspring have to be produced to obtain it. Do you remember the monohybrid
ratio?

The symbols can be written in two ways, as shown below.
