Genotypes determine which characteristics an individual will express and refers to the types of genes he or she has for a particular inheritable trait. Genes are found on chromosomes, those tightly-packed DNA structures in the cell nucleus.

Where do genotypes come from?

A genotype is an individual's collection of genes. The term also can refer to the two alleles inherited for a particular gene. The genotype is expressed when the information encoded in the genes' DNA is used to make protein and RNA molecules.

Are genotypes in chromosome?

Protein synthesis is controlled by genes, which are contained on chromosomes. The genotype (or genome) is a person's unique combination of genes or genetic makeup.
