Explanation: 

Detailed explanation-1: -In a broad sense, the term “genotype” refers to the genetic makeup of an organism; in other words, it describes an organism’s complete set of genes.

Detailed explanation-2: -With eye color, for instance, “B” stands for a brown allele and “b” stands for a blue allele. An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB.

Detailed explanation-3: -Phenotype is a description of your physical characteristics. It includes both your visible traits (like hair or eye color) and your measurable traits (like height or weight). Phenotype also refers to characteristics related to your development and behavior, like elements of your personality.

Detailed explanation-4: -Heterozygous refers to having different alleles for a particular trait. If the two versions are different, you have a heterozygous genotype for that gene. The relationship between the two alleles affects which traits are expressed.
