In this scenario, the mother has blood type A and is heterozygous (IAi). The father has blood type B and is also heterozygous (IBi).

First, please complete the Punnett square below. Add one allele into each parental allele box, and a complete genotype (such as IAIB, IBi or ii) into each offspring box. Remember that dominant alleles should always be written before recessive alleles in a genotype (IBi, never iIB). Please review my powerpoint!

BLOOD TYPE (A and B alleles are CO-DOMINANT with each other) IA = allele for type A IB = allele for type B i = allele for type O Mother allele #1: Mother allele #2:

Father allele #1:

Father allele #2:

How many different blood types are possible in the offspring?

1 2 3 4 5

What percentage of the offspring have at least one “i” allele?

0% 25% 50% 75% 100%

What percentage of the offspring have two alleles that are co-dominant?

0% 25% 50% 75% 100%

    In simple Mendelian inheritance alleles display a simple dominant/recessive relationship. There are many exceptions to Mendelian laws of inheritance. Most genes have more than two allelic forms and do not exhibit simple Mendelian inheritance. The human ABO antigens are an example of a multiple allelic trait. There are three ABO blood group antigens, IA, IB and i. The i allele is recessive to both IA and IB. A person who is homozygous ii has type O blood and does not...

    A woman has type A blood that is Rh-negative. Her father, however, had type B blood that was Rh-positive. She marries a man who is AB positive, but his mother was Rh-negative. I know that the allele for Rh positive blood is dominant (R) over the allele for Rh-negative blood (r). But I am having trouble with a 4x4 Punnett square which I am sure would be essential to solving this! I appreciate any help you could give! 1. What...
