Duplication mutation biology
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.
