In a cross between two pea plants, one with round seeds (R) and one with wrinkled seeds (r), what is the phenotype of the F1 generation if round is dominant?
Round
Wrinkled
Both
Neither
The phenotype of the F1 generation will be round seeds since round (R) is dominant over wrinkled (r).

Q: In a cross between two pea plants, one with round seeds (R) and one with wrinkled seeds (r), what is the phenotype of the F1 generation if round is dominant?
Solution: The phenotype of the F1 generation will be round seeds since round (R) is dominant over wrinkled (r).
Steps: 5
Step 1: Identify the traits of the parent pea plants. One plant has round seeds (R) and the other has wrinkled seeds (r).
Step 2: Understand that round seeds (R) are dominant over wrinkled seeds (r). This means that if a plant has at least one R, it will show the round seed trait.
Step 3: When these two plants are crossed, the offspring (F1 generation) will inherit one allele from each parent.
Step 4: The F1 generation will have the genotype Rr (one round seed allele and one wrinkled seed allele).
Step 5: Since round (R) is dominant, the phenotype of the F1 generation will be round seeds.
