What does it mean that a wrinkled-seed allele, (for example,) is recessive?

B. It "recedes" in the F2 generation when homozygous parents are crossed.

What does it mean that a wrinkled-seed allele, (for example,) is recessive?

A. The trait associated with the allele is not seen in heterozygotes.

B. It "recedes" in the F2 generation when homozygous parents are crossed.

C. The allele is less common than the dominant allele. D. Individuals with the allele have lower fitness than individuals with the dominant allele.

Explanation / Answer

B. It "recedes" in the F2 generation when homozygous parents are crossed.

An allele represents the particular form of a gene. A homozygous recessive allele combination contains two recessive alleles and expresses the recessive phenotype. For example the gene for seed shape in pea plants exists in two forms, one form or allele for round seed shape (R) and the other for wrinkled seed shape (r).
