In article <2103@aecom.YU.EDU> werner@aecom.YU.EDU (Craig Werner) writes: The plot thickens even more when you consider that the Tay-Sachs mutation actually arose at least four separate times indepen- dently (that is, there are four distinct gene patterns, all distinguishable from one another by standard molecular genetic techniques that cause a defect in the same enzyme, and thus create the Tay-Sachs trait. This is quite a large number when you consider that Sickle Cell seems only to have arisen twice. Are these four gene patterns mutually "compatible"? Stated another way, if a child inherits a different version of the TS gene from each parent, will he still develop Tay-Sachs disease? -- Rich Wales // UCLA Computer Science Department // +1 (213) 825-5683 3531 Boelter Hall // Los Angeles, California 90024-1596 // USA wales@CS.UCLA.EDU ...!(uunet,ucbvax,rutgers)!cs.ucla.edu!wales "The best diplomat I know is a fully charged phaser bank."
