Question

Help!!!!!! There are two types of pea plants: those that produce round seeds and those that produce wrinkled seeds. A single gene controls which type of seed a pea plant will produce.

An experiment shows that pea plants containing an allele for wrinkled seeds may still produce round seeds.

Based on this information, we can conclude that the allele for wrinkled seeds in pea plants is _______.
A.
recessive
B.
dominant
C.
homozygous

Answer 1

A. Recessive

Step-by-step explanation:

Answer 2

Recessive traits can remain in the gene pool even when they aren't the phenotype that is displayed. Even though a seed appears to be round, it can be heterozygous for seed shape. Thus, the wrinkles must be a recessive trait, because they remain in the genotype but they are not expressed in the phenotype over the dominant seed shape-round.
