If a dad is heterozygous for Type B blood
and a mom is heterozygous for Type A blood,
… create a Punnett Square to determine the
blood type(s) of their children?
1. Determine the trait studied.
2. Assign a letter for the dominant & recessive alleles.
3. Record the genotype of the parents.
4. Determine the F1 generation using a Punnett Square
