검증된 단계별 안내1
Understand that a Punnett square is a tool used in genetics to predict the possible genotypes of offspring from a particular genetic cross.
Recognize that it helps visualize how alleles from each parent combine during fertilization.
Use the Punnett square to list all possible allele combinations from the parents' genotypes.
Calculate the probability of each genotype by counting the frequency of each allele combination in the square.
From the genotypes, infer the expected phenotypes based on dominant and recessive allele relationships.
