Why is blood type o the most common if it has 2 recessive traits?

I think that it must be evolutionarily older. If A and B came along later in human evolution, there just hasn't been enough time for them to become the more prevalent phenotypes.

What genes are recessive traits?
These traits are called dominant traits. They will overcome the recessive gene and the dominant trait will be expressed. A recessive gene needs two alleles present in its genotype to be expressed.
Is recessive traits visible?
Sometimes. But the dominant gene will have most of the trait.
How are dominant and recessive genes related?
Dominate them. Recessive alleles do not show in your phenotype unless you have two of the same recessive allele. But if you inherit one dominant and one recessive, it is the dominant that always shows in your phenotype.
Are the dominant traits always the most common in a population?
it is because that trait is more dominant. when a dominant and a recessive trait combine it is most likely that hte dominant trait will be expressed. it is only when a recessive trait combines with an another recassive trait that hte trait gets expressed(which is rare and not so commonly occuring)
Is type O blood a recessive genetic disorder?
No surprisingly AB is not recursive at all. It is actually dominant. However it is rare. The most common blood type is O although is recessive. They believe that people with O blood type had a greater chance of surviving the black plague in the middle ages and that is why so many people have type O blood.
Are dominate traits always the most common?
Yes, there is no possibility of a Recessive trait being dominant.
What genotypic condition must be present for a recessive trait to be visible?
if the ratio had more recessive traits, like if you made a punnit square and you saw that there were more of the recessive traits (BB bb bb bb) then you know that the most common trait is the recessive one "bb" (considered as homozygous recessive ( i think))

Why do recessive trail are more common in some cases?
They're not necessarily, but they can be. When a recessive trait is more common, it likely because it was advantageous to have that trait so the species evolved to have more of it in the gene pool. Also, since dominant traits are expressed over recessive traits, natural selection has more of an effect on them.
What kind of diseases are the most common genetic diseases (?
Recessive Autosomal
How are dominant and recessive genes related?
Dominate them. Recessive alleles do not show in your phenotype unless you have two of the same recessive allele. But if you inherit one dominant and one recessive, it is the dominant that always shows in your phenotype.
Are sex-linked traits that are recessive phenotypes most often seen in men or woman?
men
What is the name of the trait that is most common in a group?
recessive
Are the dominant traits always the most common in a population?
it is because that trait is more dominant. when a dominant and a recessive trait combine it is most likely that hte dominant trait will be expressed. it is only when a recessive trait combines with an another recassive trait that hte trait gets expressed(which is rare and not so commonly occuring)
What kind of diseases of the most common genetic diseases?
recessive autosomal
What does the word dominant mean in genetics?
The dominant overpowers the recessive traits. The dominant trait is the trait the the offspring will most likely have.
