With the complexities of gene regulation and transcription, according to a new gene and a recognition of the self, "the same class (protein or RNA), functional products that encrypt, potentially overlapping, the combination of genome sequences." Gene, the basic physical and functional unit of heredity. Every gene, protein or RNA molecule with a specific function, such as the nucleotide sequences of chromosomes consists of a certain point. Classical genetics, the same biological functions according to deter them to a not managed and mutual recombination of alleles and genes are not allelic. Allelic genes, genes that are effective on the same property. Classical genetics the gene is used as a sub-unit.
