To determine the phenotype for each genotype regarding seed shape where smooth (S) is dominant to wrinkled (s), we can analyze the given genotypes:
-
SS (homozygous dominant): The phenotype is smooth seed shape.
-
Ss (heterozygous): The phenotype is also smooth seed shape, since the dominant allele (S) masks the effect of the recessive allele (s).
-
ss (homozygous recessive): The phenotype is wrinkled seed shape.
So, filling in the blanks:
- SS: smooth seed shape
- Ss: smooth seed shape
- ss: wrinkled seed shape
