SS, SS, Ss, Ss

50% - homozygous smile dimple (SS)

50%- heterozygous smile dimple (Ss)

2nd generation:

Father- SS (Timmy)

Mother- Ss (Brooklyn)

If we are going to cross multiply these genotypes, the resulting offspring would be:

SS, SS, Ss, Ss

50% - homozygous smile dimple (SS)

50%- heterozygous smile dimple (Ss)

2nd generation:

Father- Ss (Fred)
