Question

a student is predicting whether the seeds of pea plants produced by the cross shown in the punnett square. what are the phenotypes of the offspring from the cross shown? 100% round, 0% wrinkled 75% round, 25% wrinkled 50% round, 50% wrinkled 25% round, 75% wrinkled

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
