What do you believe the answer to be?

anonymous · Answer

If so what is your reasoning? We will start here.

anonymous · Answer

i think it would be 25% because one parent is colorblind and one is not. so like a 50/50 chance?

anonymous · Answer

50%***** sorry

anonymous · Answer

Well if one of them is fully on recessive and one of them is fully dominant then that would be 100% dominance because if you put this in a pedigree chart then everything would come out Xx which means that dominant would take over all 4 squares.

that makes sense so 100% is the answer? thank you very much. does the medal mean you helped me?

anonymous · Answer

no! 0% sorry

anonymous · Answer

So if colorblindness is recessive but the next child would be fully dominant...this means that the child would have a 0% of being colorblind since the Punnet Square would reveal your child would have no colorblindness and the medal and fan to me would be much appreciated. Thankyou
