By Ariela Pelaia. A dreidel is a four-sided spinning top with a Hebrew letter on each side. It is used during Hanukkah to play a popular children's game that involves spinning the dreidel and betting on which Hebrew letter will be showing when the dreidel stops spinning. Hey means halb, which means half in Yiddish. 2  If the dreidel lands with a hey facing up the spinner gets half of the pot. 3  Shin means shtel, which is Yiddish for put in.. 4  Pey means pay.. 5  If the dreidel lands with either a shin or a pey facing up the player adds a game piece to the pot.
Figure 1: Diagram of pleiotropy. A pleiotropic gene is a single gene that controls more than one trait. Â© 2008 Nature Education All rights reserved. Today, we know that Mendel's observations were the result of pleiotropy, or the phenomenon in which a single gene contributes to multiple phenotypic traits.n some instances of pleiotropy, the influence of the single gene may be direct. For example, if a mouse is born blind due to any number of single-gene traits (Chang et al. , 2002), it is not surprising that this mouse would also do poorly in visual learning tasks.
