Date: Thu, 25 May 1995 14:10:31 GMT Organization: Netcom Lines: 16 Distribution: world Message-ID: <3q26li$9pg@ixnews1.ix.netcom.com> NNTP-Posting-Host: ix-bos6-14.ix.netcom.com X-Newsreader: Forte Free Agent v0.46 I recently finished the first part of a research on population genetics. I studied the allelic frequency changes in 5 generations of 2 populations of D. melanogaster started with two different allelic proportions of yellow:wild (50%w and 50%y, and 33.3%w and 66.6%y, respectively) Despite the mating disadvantage of yellow males (faulty wind component of courtship) I ended up after the 5th. generation in both populations with a 60%y to 40% w. I observed that the yellow males hatched sooner (at least 12 hours) than their wild counterparts and they are consistently smaller in size. Since all the literature refer to the disadvantages of the yellow mutation, I would appreciate any info to corroborate the findings of the advantages cited above. Thank you!
