Question

which statement describes incompletely dominant alleles?
two alleles that blend to create an intermediate phenotype
two alleles that are expressed separately and equally
any allele whose presence can be masked by another allele
any allele that can hide the presence of a different allele

Explanation:

Incomplete dominance is a form of inheritance where neither allele is completely dominant over the other. Instead, the two alleles blend to create an intermediate phenotype. For example, in snapdragons, a red - flowered plant (RR) crossed with a white - flowered plant (rr) results in pink - flowered (Rr) offspring.
The second option describes codominance (e.g., AB blood type where both A and B alleles are expressed). The third option describes a recessive allele. The fourth option describes a dominant allele.

Answer:

two alleles that blend to create an intermediate phenotype
