The location of cl

cl was originally mapped relative to a, lg2 and ts4 by Robertson (MNL 33:63, 1959). These data place cl between Lg3 and d on the short arm of chromosome 3. Recent 2-point crosses between cl and d, and cl and Lg3, appear to confirm this location. The results shown in Table 1 indicate that cl is about 17 map units from d, while the data in Table 2 indicate that cl is about 5 map units from Lg3. Given that Lg3 and d are 25 map units apart (MNL 58:255, 1984), these data confirm the current location of cl. The results of a 3-point test cross will be scored this summer.
