The best description of a recessive allele is:
**does not determine phenotype when a dominant allele for the same trait is present.**
Recessive alleles only express their traits phenotypically when an individual has two copies of the recessive allele (homozygous recessive). If a dominant allele is present, it will mask the expression of the recessive allele.
