Grey was crossed with white. 5 grey and 0 white were formed. The genotype of the grey parent will be

    1. Gg
    2. GG
    3. Both a and b
    4. gg

As, 5 progenies are not showing large enough data to conclude that grey parent has no g allele to contribute for white progeny. Hence the genotype of the grey parent can be GG or Gg.
