摘要: Genetic maps of chromosomes 2 and 4 constructed from pair-wise lod score data family studies regional assignments for markers are presented. Two loci mapped on chromosome multiple crossing-over is suggested as an explanation the poor fit to in females. The best map gives genetic locations five with Stoltzfus (SF) blood group distal MNS long arm GC close centromere short arm. This position outside its provisional assignment possible reasons this discrepancy discussed. GM-PI linkage has a less than-1.0 suggesting that it may be excluded chromosome.The 2–5 also shown.
