(note that different genotypic abbreviations are used for mendelian extensions to distinguish these patterns from simple dominance and recessiveness). Mendelian inheritance is a type of biological inheritance that follows the laws originally proposed by gregor mendel in 1865 and 1866 and re-discovered in. Human genetics by: omar m jacalne extension of mendelian inheritance. Mendel's laws fail to adequately explain some phenomenon like mitochondrial gene inheritance and inheritance due to linkage between genes.
