Explanation:
Detailed explanation-1: -In this example, there are two different alleles for the eye color gene: the E allele for red eye color, and the e allele for brown eye color. The red (E) phenotype is dominant to the brown (e) phenotype, so heterozygous flies with the genotype Ee will have red eyes.
Detailed explanation-2: -The phenotype of an organism is its physical characteristics.
Detailed explanation-3: -In an organism, tall phenotype is dominant over recessive phenotype, and alleles are designated as T and small t, respectively.
