From an evolutionary perspective, why do we have multiple different blood types and what advantages or disadvantages does that entail?
Evolutionary advantage of the different blood groups?
What are advantages and disadvantages of each Blood groups? What are the different blood groups? What are the different human blood groups and types? What are the blood groups? What are some blood cell adaptations? What are the compatibility of blood types? Do animals have blood groups? What is the disadvantage of the B negative blood group? What happens when both parents have the same blood group? If both parents have blood group B+, what will be the genetics of the child? What are white blood cells' adaptations? Are there 6 blood groups? When parents are both blood group b positive then what is child's blood group? When and why did we evolve RH negative blood? Can we have kids with the following blood group combination - AB+ (male) and O- (female)? Can we have kids with the following blood group combination: o+ (Male) and o+ (female)? Can we have kids with the following blood group combination: o-(Male) and o+ (female)? What are characteristics only red blood cells posses? How do blood banks justify stocking rare blood types? Is the O+ blood group the universal donor or not? Why are some blood types rare? What could be the blood group of a child if his parents are both B positive? Why is O the most common blood type in humans even though it is a recessive trait? What is the difference between animal blood and human blood? How were the creatures in "True Blood" created? Why do blood type O and B have a high compatibility? How do I differentiate between human and animal blood? Is the O- blood group the universal donor or not? What is the probability that a baby have AB blood group if his parents has A and B blood group? If I have blood type AB+ what blood types would my parents have?
