In the most basic terms, genome is the genetic material of an organism. It is what tells the organism what to be and how to be. The genome is coded in DNA, or in RNA for many types of viruses. The term, genome, was coined in the 1920, as a portmanteau of gene and chromosome.
Difference Between Gene and Allele. A gene is a part of the DNA. Alleles on the other hand refer to different versions of the same gene. Genes are the different parts of the DNA that decide the genetic traits a person is going to have. Alleles are the different sequences on the DNA-they determine a single characteristic in an individual.
