A dominant allele K is necessary for normal hearing. A dominant allele M on a different locus results in deafness no matter what other alleles are present. If a kkMm individual is crossed with a Kkmm individual, what percentage of the offspring will be deaf?

    1/4= 25%

    Let me TRY this problem as I am also working on genetics right now. I did a cross off Kk x kk and 0.5 are deaf. Also crossing Mm x mm 0.5 deaf. Multiply the b/c they are independent but occur together? = 0.25 = 25%¿¿?? If someone could check this? Lol

    I was trying to solve for it but it gave me something completely different. I usually pair them and do the punett square so kM km kM and km with Km Km km km

    however doing this method I get 50% of them will have the allele M which throws me off because that doesn't look right ( and isn't right anyway) However the method used is right. I think O.o

    You did a dihybrid cross?

    Would using a dihybrid cross be wrong ? O.O

    I just checked my notes and the way you did it is just fine for probabilities but i don't understand how a punett square can't do it x.x

    Yeeeh. I' still havent mastered pedigree yet. I just went over codominance and incomplete dominance and the basics.
