Recessive Genes: Common
Why are recessive genes more common then dominant genes?
Are you asking why recessive genes CAN be more common than dominant ones? Or
why ARE they more common? They aren't more common in general, but there are
situations where a recessive gene is more common. It depends on what the gene
does for one thing. Blue eyes is recessive but it is common in the
population. One reason is because it's not fatal to have blue eyes and in
some cases it increases chances for mating ( ie. some people find them more
attractive!) The gene for Huntington disease is dominant but most people
don't have it, so recessive is most common. Type O blood is recessive, but
it is the most common in the population.
