Chapter 16, Problem 44TC

Let’s assume that human height is a polygenic trait

determined by three genes: A, B, and C. For each gene,

there is a tall allele and a short allele. We’ll use T and S

to indicate these. Seven people have the following geno-

types: A_SA_SB_SB_SC_SC_S, A_SA_TB_TB_SC_SC_T, A_TA_TB_TB_TC_TC_S,

A_SA_TB_TB_TC_TC_S, A_TA_TB_TB_TC_TC_T, A_SA_TB_SB_TC_SC_S,

A_SA_TB_SB_SC_SC_S. Rank them from tallest to shortest.
