In pea plants, two alleles for plant height are present: T and t. If a plant shows the recessive phenotype, its genotype would most likely be:

In humans, there are three alleles for blood type: IA, IB, and i. Both IA and IB are dominant while i is recessive. If a person has blood type AB and expresses the A and B molecules simultaneously on their red blood cells, this is an example of:

Based on Mendelian inheritance, would it be necessary to know both the genotype and phenotype for an organism when attempting to predict the inheritance pattern for a trait in offspring?
