Physical appearance of a trait
A
Genotype
B
Phenotype
C
Heterozygous
D
None of the above
Explanation: 

Detailed explanation-1: -Phenotype refers to an individual’s observable traits, such as height, eye color and blood type. A person’s phenotype is determined by both their genomic makeup (genotype) and environmental factors.

Detailed explanation-2: -The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. An organism’s phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.

Detailed explanation-3: -Definition. A phenotypic trait is an obvious, observable, and measurable characteristic of an organism; it is the expression of genes in an observable way. An example of a phenotypic trait is a specific hair color or eye colour.

Detailed explanation-4: -Physical appearance resulting from genotype is called phenotype. The phenotype is what you observe from the genes expressing themselves. For example, if you see that your eyes are brown, you have genes that express the color brown for your eyes.

Detailed explanation-5: -The correct option is C. Phenotype. A phenotype is the composite of an organism’s observable characteristics or traits, such as its morphology, development, biochemical or physiological properties, phenology, behavior, and products of behavior.
