Abstract:
A systematic search for restriction fragment length polymorphisms (RFLPs) on the human Y chromosome was performed. DNA samples from 16-34 individuals were screened with five restriction enzymes and 12 Y-chromosomal probes, 3 of which detect lowly repetitive sequences and 9 of which are apparently single copy in genomic DNA. None of the single-copy probes revealed any variation. The repetitive sequence probe p21A1 (DYZ?) revealed a TaqI RFLP with q = 0.05. The frequency of fixed point mutations in Y-chromosomal DNA outside the pseudoautosomal region is probably less than 1 in 18,000 bp.
