Pleiotropy is a phenomenon that occurs when a single gene affects several characteristics of living creatures. nucleus, in biology, a specialized structure occurring in most cells (except bacteria and blue-green algae) and separated from the rest of the cell by Pleiotropy can be caused by a gene mutation. Here, the gene of seed coat colour was not the only one responsible for its colour but also for the axil pigmentation and flower. Gregor Mendel, the father of genetics made various interesting observations during his study of inheritance regarding the colour of different plant components. Hence, instead of affecting only one characteristic, the colour gene affects three. Pleiotropy is a term used to describe the multiple organ systems affected by this condition: peripheral nervous system (neurofibromas), vasculature (renal arteries), brain (learning disabilities), endocrine (pheochromocytoma), skin (caf-au-lait spots), and skeleton (dysplasias and scoliosis). many traits (a condition termed pleiotropic). However, Mendel observed that the colours were always related to two different features: the seed coat colour and the colour of axils.
