Question

a punnett square is generally used to
multiple choice
predict the genotypic ratio among the offspring.
determine the phenotype of each parent from its genotype.
predict the number of offspring that will exhibit each genotype.
determine the genotype of each parent from its phenotype.

Explanation:

A Punnett square is a tool in genetics used to visualize the possible genetic combinations from parental gametes. Its primary function is to predict the expected genotypic ratio of offspring by crossing parental genotypes. The other options are incorrect: it does not determine parent phenotypes/genotypes from one another, nor does it predict exact offspring numbers (only ratios).

Answer:

A. predict the genotypic ratio among the offspring.
