Question

what is the primary purpose of using a punnett square? to study environmental impacts on genes to show the exact genetic makeup of parents to map the entire genome of an organism to determine the probability of genotypes and phenotypes in offspring

Explanation:

A Punnett square is a genetic tool that uses the known genotypes of parent organisms to predict the possible genetic combinations (genotypes) and resulting physical traits (phenotypes) of their offspring, along with the probability of each outcome. The other options describe unrelated genetic or environmental research goals.

Answer:

To determine the probability of genotypes and phenotypes in offspring
