Based on Mendel’s experimental observation and conclusion on pea plants, he proposed four postulates including one that each phenotypical characteristic are controlled by a pair of unit factors also known as alleles that separate independently in gametes. Although Mendel’s contribution to genetics isn’t wrong, there are some exceptions of inheritances that do not follow Mendel’s principles. Non-mendelian inheritance traits include maternal effects, epigenetics, and extranuclear genes. What makes traits non-mendelian is if their phenotypic patterns do not follow in accordance with Mendels laws.
Maternal effects being one of the many exceptions to Mendels laws, involves the pattern of inheritance in which the phenotype of the offspring for a
