Yes, human biology is not limited to a four block punnet square, it is much more complex than that.
yes
No, the only difference is in the shape of certain proteins.
Type B blood is rarer than type A and O, but more common than type AB. Individuals with type B blood have antigens in their blood that will attack other blood types if introduced to the body, leading to a hemolytic reaction.
No particular blood type is at more risk for high blood pressure than any other type. It is mostly stress, diet, and genetics that affect blood pressure.
Human blood type is determined by codominant alleles.
Yes, the red blood cells are the most common type of blood cells, they are followed by white blood cells frequency. There are also, platelets, which aren't technically considered cells, but are more frequent than white blood cells and less frequent than red blood cells.
If you have type O blood, your blood can be given to anyone. You are called a universal blood donor
This is called co-dominance. This is when 2 or more alleles are expressed at the same time. In other words they both affect the phenotype. In the example of human blood ABO type we have an allele for A = IA, B= Ib O=iIAIb = AB blood typeIbIb = B blood typeIai = AIaIa = A bloody typeIbi = B blood typeii = O blood type
No, human fossils are among the rarest type of fossils. Fossils of plants and marine organisms are far more abundant and have been found in greater numbers than human fossils.
Yes, it is possible for your children to have a completely different blood type than you or your spouse. This can make it more difficult if your son is ever in need of a transplant.
AB negative is the rarest blood type. AB positive is the second rarest blood type. The negative blood types are more rare than the positive. The common blood type is o.
