In a population of rabbits, a recessive coat characteristic is much more common than the dominant one. What does this show?

That dominance does not decide how common a characteristic isՃիշտ պատասխան
That the recessive allele has turned into a dominant one
That the record of which allele is dominant must be wrong
That a dominant characteristic is always the rarer one

Բացատրություն

How often a characteristic turns up depends on how common its allele is in that population, not on which allele masks the other when the two meet. Dominance is a rule about what happens inside one organism, so it places no limit at all on the numbers counted across a whole population.
