Please become accustomed to provide decent context info of your problem.
It is always helpful to support a request with system info like OS and shell, related environment (variables, options), preferred tools, and adequate (representative) sample input and desired output data and the elaborate (!) logics connecting the two, to avoid ambiguities and keep people from guessing.

For your above problem, try
Code:
awk '
        {split ("",  C)
         for (i=6; i<=NF; i++) C[$i]++
         CM = C["homo"]
         CR = C["hetero"]
        }
(CM > 1) && !CR ||
(CR > 1) && !CM ||
NR == 1
' file
