How are Punnett squares and pedigrees different?

Question

Quizplus · Accepted Answer

Punnett squares are diagrams that are used to determine the risk of offspring being affected when the mode of transmission and the parents' carrier status are known. It is based on genotype. Pedigrees show relationships and expressed traits or disorders, the phenotype. Neither pedigrees nor Punnett squares by themselves can identify actual carrier status. Pedigrees can suggest carrier status but not prove it. Punnett squares require the genotypes for a specific trait to be known for both parents to demonstrate probabilities.
