Pleiotropy occurs when one gene influences two or more seemingly unrelated phenotypic traits, an example being phenylketonuria, which is a human disease that affects multiple systems but is caused by one gene defect.Consequently, a mutation in a pleiotropic gene may have an effect on some or all traits simultaneously.he underlying mechanism is that the gene codes for a product that is, for example, used by various cells, or has a signaling function on various targets. A classic example of pleiotropy is the human disease phenylketonuria (PKU).
Along with regulating wing development, the vg gene is also pleiotropic. Indirectly, the gene changes the number of egg strings in a fly's ovaries, alters the position of bristles on a fly's scutellum, and decreases the length of a fly's life (Caspari, 1952; Miglani, 2002).he term pleiotropy is derived from the Greek words pleio, which means many, and tropic, which means affecting.. Genes that affect multiple, apparently unrelated, phenotypes are thus called pleiotropic genes (Figure 1).
