From quora:
A genome and a genotype are related concepts in genetics, but they refer to different things:
Genome: The genome refers to the complete set of genetic material (DNA in most organisms) present in an organism. It includes all the genes, as well as non-coding sequences of DNA. The genome contains all the hereditary information necessary for the development, functioning, and reproduction of an organism.
Genotype: The genotype refers to the specific genetic makeup of an individual, with respect to a particular trait or traits. It represents the combination of alleles (alternative forms of a gene) that an individual possesses for a given set of genes. The genotype determines the genetic potential of an organism and influences its observable characteristics or phenotype.
In summary, the genome is the entire genetic material of an organism, while the genotype refers to the specific genetic composition of an individual with respect to certain traits. The genotype is a subset of the information contained within the genome.
