Context: This passage describes the shell banding trait in Cepaea snails:
Cepaea snails live on land in many parts of Europe. The shells of Cepaea snails can have different colors and patterns. Banded shells have dark bands, or stripes, that spiral around their surfaces. Unbanded shells do not have bands.
In a group of Cepaea snails, some individuals have a banded shell and others have an unbanded shell. In this group, the gene for the shell banding trait has two alleles. The allele for an unbanded shell (b) is recessive to the allele for a banded shell (B).
This Punnett square shows a cross between two Cepaea snails.
What is the probability that a Cepaea snail produced by this cross will be homozygous recessive for the shell banding gene?
A. 4/4
B. 0/4
C. 1/4
D. 3/4
E. 2/4
