How are blood types related to Mendels principles of alleles?

For example, Mendel's Law of Dominance is disobeyed in the case of blood typing, in which two dominant genes are expressed simultaneously. ... Blood type is dictated by 3 separate versions of the same gene: dominant A, dominant B, and the recessive O. Each person has two alleles – one from mom and one from dad.

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.
