A scientist crosses a brown guinea pig with a white guinea pig several times, he has a
phenotypic ratio of 1 brown, 2 spotted and 1 white, is this an example of complete
dominance or incomplete dominance? Explain your answer.
no
This is an example of incomplete dominance because neither the brown nor the white allele is dominant. Assuming that the genotype for the brown guinea pig is Bb the white guinea pig is Ww there is a 50% possibility that the offspring is mixed colors since the dominant trait isn’t completely able to mask the recessive one.
