Verified step by step guidance1
Understand the concept of phenotype: A phenotype refers to the observable physical or biochemical characteristics of an organism, as determined by both genetic makeup and environmental influences.
Differentiate between genotype and phenotype: Genotype is the genetic makeup of an organism, while phenotype is the expression of the genotype in the form of physical traits.
Identify examples of genotype: Terms like 'heterozygous genotype' and 'homozygous genotype' refer to the genetic composition of an organism, not the physical traits.
Recognize examples of alleles: A 'recessive allele' is a variant form of a gene that can be masked by a dominant allele and does not directly describe a physical trait.
Identify the phenotype in the options: 'Blue eye color' is a physical trait that can be observed, making it an example of a phenotype.
