None of the above

Explanation:
Detailed explanation-1: -A Punnett square is a chart that allows you to determine the expected percentages of different genotypes in the offspring of two parents. A Punnett square allows the prediction of the percentages of phenotypes in the offspring of a cross from known genotypes.
Detailed explanation-2: -Punnett squares use mathematical probability to help predict the genotype and phenotype combinations in genetic crosses.
Detailed explanation-3: -The Punnett square in Figure 8 can be used to consider how the identity of the unknown allele is determined in a test cross. Breeding the flies shown in this Punnett square will determine the distribution of phenotypes among their offspring.
