Answer

Explanation:

Step1: Identify dominant and recessive alleles

Assume R is dominant (round - shaped seeds) and r is recessive (wrinkled - shaped seeds).

Step2: Analyze genotypes in Punnett - square

The genotypes of the offspring are RR, RR, Rr, Rr.

Step3: Determine phenotypes

Since RR and Rr both express the dominant trait (round seeds), all offspring have round seeds.

Answer:

100% round, 0% wrinkled
