WebThe chromosomes are beset with genes and consequently chromosome duplication means in a way the duplication of genes. Genes always arise from existing genes although the material for the synthesis comes from nutritional sources. The newly formed gene is an exact replica of the parent gene. WebEvolution by gene duplication is an event by which a gene or part of a gene can have two identical copies that can not be distinguished from each other. This phenomenon is understood to be an important source of novelty in evolution, providing for an expanded repertoire of molecular activities. biomic auth

"WebGene duplication mutations have been observed to arise in bacteria (Horiuchi et al., 1962; Rigby et al., 1974) and yeast (Hansche, 1975) that have been grown in a chemostat on limiting concentrations of growth substrate. Such mutant strains possess a gene duplication that causes an increase in the production of a protein with an essential activity. " - Duplication mutation biology
