Abstract excerpt
We constructed diploids of Saccharomyces cerevisiae homozygous for LEU2 and carrying one, two, or four copies of leu2 at ectopic locations and determined the frequency of 3+:1- (LEU2:leu2) meiotic tetrads. Gene conversion between a LEU2 recipient and a leu2 ectopic donor occurred at the same frequency as did gene conversion between allelic copies of LEU2 and leu2. An increase in the number of possible ectopic...
