Multiple Choice
Dominant alleles are always expressed when present. Recessive alleles are not expressed when the dominant allele is also present. Look at the two alleles for fur color. Which allele is dominant, and which fur color does it produce?
F, black fur
F, white fur
f, black fur
f, white fur
