Question

In pea plants, round (R) is a dominant trait, and wrinkled (r) is a recessive trait. Which combination would result in wrinkled seeds?

Question 3 options:

RR


Rr


rr


ww

Answer 1

rr

Step-by-step explanation:

Answer 2

Answer: rr

Explanation:

• For any given gene there exists two or more variant forms known as the alleles.

• The allele can either be dominant or recessive.

• A dominant allele is the one which determines the phenotype in both heterozygous and homozygous condition whereas the recessive phenotype is only shown in case of a homozygous condition.

• Since the trait of wrinkled seeds is determined by a recessive allele, it is necessary for the allele r to be present in homozygous condition

• Therefore the genotype should be rr.
