Why is blood group 'o' positive more commonly found than other groups?

how does it happenWhy is blood group 'o' positive more commonly found than other groups?
anthropologists will share u all humans have blood type O. as we moved to different geographic regions, adapted different dietary patterns, some cultures devour more dairy, somemore meat, some started agriculture 10,000 years ago, so we formed different blood proteins also known as alleles such as A and B and combinations.
heaps scientists say that blood type O is within general more resistant to disease, so when a disease struck a population, the great majority of people that remained be type O.
did u know blood type A has a more possibility to get cancer?
don't take freake out plz. lolz- don't know how relevant ur blood type is.
some foods are better for some blood types. type O generally hold stronger stomach acid, so they can digest meat better. type Acan digest grains pretty powerfully, type B-dairy products.
different populations of the world also have more of A and B than the others, but O is other more than 50 percent except some european countries where the population may own 45 percent A, 48 percent O and 7 percent B. An estimate.
As for Rh positive or negative, Rh- is a recessive trait. So the proportion of Rh- society is always getting smaller.
a recessive trait is a trait that when the child is born to a Rh positive parent and a Rh- parent, probability are he will more than likely enjoy a positive blood group.
