Answer:
The punnet square will be completed as follows:
T t
T TT Tt
T TT Tt
A punnet square can be described as a diagram which shows the results of a cross.
The cross shows that the female parent carries homozygous alleles, TT, whereas the male parent carries heterozygous alleles, Tt.
The offsprings from this cross will have 50% probability of being homozygous as the female parent and will have a 50% probability of being heterozygous like the male parent.
