The hair, wart and level genes all are located on the same chromosome. Based on the segregation data shown below, what is the order of these genes on that chromosome?
Dominance relationships
HH = hairy WW = warty ZZ = top
Hh = hairy Ww = warty Zz = top
Hh = hairless ww = wartless zz = bottom
Cross h w z x h w z
H W Z h w z
Progeny
hairy warty top 560
