Question
Normal hearing in humans depends upon the presence of at least one dominant gene from each of two pairs, D and E. If you examined the collective progeny of many DdEe X DdEe marriages, what phenotypic ratio would you expect?

Normal hearing in humans depends upon the presence of at least one dominant gene from each of two pairs, D and E. If you examined the collective progeny of many DdEe X DdEe marriages, what phenotypic ratio would you expect?Explanation / Answer
DEDE : 1 : DdEe : 2 : dede 1
Thus, the progeny obtained will be in 1:2:1 ratio, exhibiting completely dominant, heterozygous and homozygous recessive traits respectively.
