1. Imagine that you are studying two parents who are considering having children. One parent is has the genotype IAi and the other has the genotype IBi. Create a Punnett square to calculate the possible genotypes of their children. Answer? Part 3 Punnett?
Part 3: Multiple Alleles—Predicting Blood Types of Offspring
As you read in the online lab, human blood type is determined by multiple alleles that show a type of inheritance called codominance. Recall that the alleles that determine blood type are IA, IB, and i. IA and IB are both dominant over i, while neither IA nor IB is dominant when they combine. Use this table to help you determine the genotypes associated with each blood type.
Blood Type Allele Possible Genotype(s) Possible Allele(s)
A IA AA or AO IAIA or IAi
B IB BB or BO IBIB or IBi
AB IAIB AB IAIB
O i OO ii

1 Answer
This is a one-trait cross,
Human blood types, A, B, and O are the alleles. The first two are codominant to each other while dominant to O. Hence,
The progeny are one
