Multiple Choice

In the allele "Pp", will the dominant or recessive trait appear?

Explanation:
The trait shown is determined by whether a dominant allele is present. In the genotype Pp, there is one dominant P and one recessive p. The dominant allele expresses the trait even when a recessive allele is also present, so the organism shows the dominant trait. Only if both alleles were recessive (pp) would the recessive trait appear. Co-dominant and incomplete patterns involve different ways alleles interact, but they don’t apply to a single dominant/recessive pair like Pp.
