What are the possible genotypes and phenotypes of the offspring from a cross between a heterozygous male with type A blood and a heterozygous female with type B blood? What is the Punnett square and what are the genotypes and phenotypes?

To determine the possible genotypes and phenotypes of the offspring from a cross of a heterozygous male with type A blood (genotype I_AI_O) and a heterozygous female with type B blood (genotype I_BI_O), we can use a Punnett square.

First, let’s set up the Punnett square:

• Father’s alleles: I_A and I_O
• Mother’s alleles: I_B and I_O

This leads us to the following possible genotypes for the offspring:

• I_AI_B (Type AB)
• I_AI_O (Type A)
• I_BI_O (Type B)
• I_OI_O (Type O)

In summary, the possible genotypes of the offspring are:

• I_AI_B
• I_AI_O
• I_BI_O
• I_OI_O

And the corresponding phenotypes will be:

• Type AB
• Type A
• Type B
• Type O
