What were Punnett squares developed to do?

to predict the probability of offspring phenotypes

to predict the probability of offspring genotypes

neither of the above

Answer: to predict the probability of offspring genotypes

Explanation: Punnett squares are developed to predict the probability of offspring genotype. Punnett square is a square shaped diagram used for predicting the possible genotypes of a cross between two organisms. Punnett square is named after Reginald C. Punnett, who invented the approach. In punnett squares, the genotypes of the parents are written on the top and left hand side of the square while the possible genotypes of their offsprings are written in the boxes.
