Date: Thu, 25 May 1995 14:06:08 GMT Organization: Netcom Lines: 17 Distribution: world Message-ID: <3q26db$9m0@ixnews1.ix.netcom.com> NNTP-Posting-Host: ix-bos6-14.ix.netcom.com X-Newsreader: Forte Free Agent v0.46 I have recently completed the first part of a research on population genetics in which I observed the changes in allelic frequencies between wild and yellow mutant. Despite the mating disadvantage that the yellow mutant males are known to have during the courtship, the final allelic frequencies I ended up with after 5 generations in two populations started with different initial proportions of yellow to wild, favored the yellow mutants 60:40. I observed that the yellow males hatched much sooner (at least 12 hours) than the wild males, and they are also consistently smaller in size than their wild counterparts (faster DNA synthesis => smaller size of eventual adult??). These are advantages that I observed but could not corroborate with current literature. Does anybody know something about this??? Thank you! Cintia Hongay Senior Undergrad.
