Five human matings numbered $1-5$ are shown in the following table. Included are both maternal and paternal phenotypes for ABO and MN blood-group antigen status. Each mating resulted in one of the five offspring shown to the right (a-e). Match each offspring with one correct set of parents, using each parental set only once. Is there more than one set of correct answers?

Key Concepts

Punnett Squares

Punnett squares are a visualization tool used in genetics to predict the outcome of a cross between two individuals. By mapping out potential gametes and their combinations, these diagrams help in determining the possible genotypes and resulting phenotypes of offspring.

Mendelian Inheritance

Mendelian inheritance describes how traits are transmitted from parents to offspring through discrete units of inheritance called genes. It emphasizes how dominant and recessive alleles interact in predictable ratios, providing a foundational framework for understanding genetic crosses.

Alleles and Phenotypes

Alleles are the different versions of the same gene that can result in variations of a trait. The set of alleles an individual carries, known as the genotype, determines the observable characteristics, or phenotype, providing the basis for analyzing how traits like blood groups are inherited.

Blood Group Inheritance

Blood group inheritance, such as in the ABO and MN systems, involves unique combinations of alleles that interact via dominance or co-dominance. These interactions dictate the phenotype seen in blood types, making the analysis of parental and offspring blood group data crucial for predicting inheritance patterns.

Multiple Solutions in Genetic Problems

Genetic problems sometimes allow for more than one valid solution or possible set of parental matches because the observed phenotype can be produced by different genetic combinations. This highlights the importance of considering multiple hypotheses when deducing the underlying genetics from phenotype data.
