The __________ allele contributes to the phenotype if one or two copies are present in the genotype

Recessive allele

• The allele that contributes to the phenotype ONLY when two copies of it are present

• The allele that contributes to the phenotype if one or two copies are present in the genotype

• When each allele in a heterozygous individual influences the phenotype. The result is a blend of the phenotypes
