<h3>What is Genotype?</h3>

An organism's genotype is made up of all of its genetic components. The alleles or variations that a person holds in a specific gene or genetic region are also referred to as the genotype.

The amount of copies of each chromosomes found in that species, also known as ploidy, determines how many alleles a person can have for a certain gene. In diploid organisms like humans, there are two complete sets of chromosomes, which means that each person has two different alleles for each gene. Homozygous refers to a genotype where both alleles are the same. Heterozygous refers to a genotype when there are two distinct alleles.

Phenotype, the observable qualities and attributes of an individual or creature, is influenced by genotype.
