Abstract
The region of yeast chromosome III between the HIS4 and LEU2 genes has an unusually high frequency of meiotic recombination. In order to determine the pattern of cross-over and gene conversion events, we constructed a strain with a number of heterozygous markers in this 25-kb interval. We found that very high levels of reombination are localized to regions of DNA near HIS4. In addition, analysis of the patterns of co-conversion of adjacent markers suggests that there is more than one initiation site contributing to recombination of HIS4.
