The absence of isolating mechanisms being associated with many autosomal regions, including some large inverted regions that separate the strains, suggests that these phenotypes may not be caused by genes spread throughout the genome. WebNon-Mendelian inheritance is any pattern in which traits do not segregate in accordance with Mendel's laws.These laws describe the inheritance of traits linked to single genes on chromosomes in the nucleus.
