Does each square on a "punnet square" represent 4 offspring or does it represent the odds of one offspring?

Explanation:

Punnet square is a square diagram used to predict the genotypes of the offspring of a particular cross or breeding experiment.

It represent 4 offsprings of the cross between two parents. Each punnet contain the alleles in the right combination and proportion.

Punnet square is use to determine the percentages of different genotypes present in the offspring of two parents and to determine missing alleles in a cross.

it can also be used to predict the percentages of phenotypes in the offspring usually from a parents with known genotypes.
