In ogres nose type results from a genetic maternal effect where the autosomal allele for a warty nose (w) is dominant over the allele for a smooth nose (w) Shrek's third cousin once removed, Shrekina, has a warty nose with a w*w genotype. She marries Golothm, a male, smooth nosed ogre with a ww.genotype and they have a warty nosed daughter, Mary.

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
