Answer 2

The chart is attached below:

• ABO blood group in humans is determined on the basis of antigens and antibodies present in the plasma.
• There are three alleles that determine the human blood group, these are ia, ib, and io.
• ia and ib are dominant genes and when present together show co-dominance (like in blood group AB). io on the other hand is a recessive gene.
• Another factor called the rhesus factor determines whether the blood group is positive or negative.
• Rh+ is dominant while Rh- is recessive.
