  • Title: The search for Y chromosome polymorphism is extended to negroids.
    Author: Spurdle A, Jenkins T.
    Journal: Hum Mol Genet; 1992 Jun; 1(3):169-70. PubMed ID: 1363868.
    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.
