Explanation:

A Punnett square is a diagram used to predict the genotypes of a particular cross or breeding experiment. In a Punnett square, the horizontal rows represent the alleles from one parent, and the vertical rows represent the alleles from the other parent. This allows for the visualization of all possible combinations of alleles that can be inherited by the offspring.

Answer:

alleles from each parent
