WebMar 8, 2024 · Molecular basis of inheritance involves the study of genes, genetic variations and heredity. It explains how an offspring looks similar to the parents. DNA, RNA and genetic code form the basis of the molecular basis of inheritance. They transmit the hereditary genes from the parents to the offspring. WebAs shown in the diagram above, the inheritance pattern of mitochondrial DNA is different from that of nuclear DNA.
