Gregor Mendel described laws of inheritance many years before the discovery of the DNA. Know the laws and the genius behind them.
3. Non-mendelian Inheritance Review
Epistasis, codominance, incomplete dominance, lethal genes, pleiotropy, multiple alleles, polygenic inheritance are all non-mendelian inheritances.
