RELATIVE POSITIONS OF CHROMOSOME 1 LOCI Fy, PGM1, Sc, UMPK, Rh, PGD AND ENO1 IN MAN

Abstract
Ongoing linkage studies of red cell antigens and enzymes in many families along with concentration on a large Mennonite kindred segregating for Sc have resulted in lods, recombinant: nonrecombinant counts and multi-point information which support an order with approximate recombination fractions as measured in the male as follows: [Fy[Duffy]-.25 PGM, [phosphoglucomutase]-.20-Sc-<.05-UMPK[uridine nonophosphate kinase]-.15-Rh-.20-PGD [phosphoglucodehydrase] with ENO, [enolase] close to PGD].
