Type ab blood: 5% of the population: rh blood typing: Rh-: 15% of the population: mns enzyme blood typing: N type enzyme: 22% of the population. M type enzyme: 30% of the population. S type enzyme: 48% of the population: 75% of males have a y chromosome in their red blood cells, dna analysis: Chance of having two persons with identical dna patterns is 30-100 billion to 1.
