Non-Mendelian genetics, also known as Non-Mendelian inheritance, is a term that refers to a system of inheritance that does not follow Mendel's laws.

Extranuclear inheritance
Extranuclear inheritance is the transmission of genes that occur outside the nucleus. It often happens in mitochondria and chloroplasts. Viruses and bacteria can also do so. Either one or two parents can pass down genetic material.

Genomic imprinting
Genomic imprinting works the same way as conventional inheritance, except that the genes are epigenetically marked before being passed down.
