Abstract:
DNA samples of Negroid and Caucasoid origin were used to screen for Y-specific RFLPs. A total of 7 Y chromosome probes and 13 restriction enzyme digests were used to examine a conservative estimate of 20000bp. No new Y-specific polymorphisms were revealed. The paucity of polymorphism on the Y appears to be unrelated to possible bottleneck effects during raciation.
