Multiple alleles
There are several variations of Mendelian genetics which include: ________, Codominance, Incomplete Dominance, Pleiotropy, Polygenetic Inheritance, and X- Linked Inheritance.

New cards
There are several variations of Mendelian genetics which include
IA (A antigen is on the red blood cells), IB (B antigen is on the red blood cells), and i (there are neither A nor B antigens on the red blood cells)
