If a corn plant had Purple kernels and a smooth seed shape, what could its possible genotype be? Choose all that apply.
Mumz [18]

Answer: Its possible genotypes are PPSS, PPSs, PpSS, and PpSs.

Explanation: If P represents the allele for purple kernel and S represents the allele for smooth seed shape; if P and S are dominant alleles, PP and Pp will manifest outwardly as purple kernel because P is dominant and will be able to express itself whether in a homozygous or heterozygous state. Similarly, SS and Ss will manifest outwardly as smooth seed shape because S is dominant and will be able to express itself whether in a homozygous or heterozygous state.

Therefore, PPSS, PPSs, PpSS, and PpSs will appear outwardly as purple kernel and smooth seed shaped corn plant.
