[Strategies for detecting restriction polymorphisms of Y chromosome sequences].
Six cloned genomic sequences from the human Y chromosome were used for the detection of restriction polymorphisms in a panel of unrelated DNAs. Three sorts of strategies for the detection of polymorphisms were used: (a) mixing individual DNAs restricted by several endonucleases, (b) separated restrictions of the DNA library members with six different restriction enzymes, (c) individual DNA digestion with TaqI and MsqI. Results show that restriction polymorphisms are detected only rarely; this result can be explained by exemption of most of the Y chromosome from meiotic pairing and exchange.
