(this is a punnett square btw) sponge bob squarepants is heterozygous for his square shape and his partner, spongebarbra, is round. create a punnett square to show the possibilities that would result if they had children

A punnet square can be described as a diagram which illustrates the outcomes of a cross.

Let's consider the alleles in bob squarepants is Ss and the alleles for his partner spongebabra are ss. The punnet square can be drawn as follows:

       s            s

S    Ss       Ss

s    ss        ss

The results from the punnet square show that there is a 50% chance that the offsprings will be heterozygous for square shape just like squarepants. There is also a 50% chance that the offspring produced will be round like spongebarbra.
