Jorgensen (BGN 4: 43 ) has located the ml-o gene distal to Jmlg Singh and Tsuchiya (BGN 4 :66 ) have located the centromere by telotrisomic analysis between the k locus and the lg4 locus. Allelism tests by Eslick (BGN 4: 9 ) confirm the allelism of gs1 and cer-q. Haus (BGN 4: 31 ) has verified the allelism of gl3 and cer-j and of gl3 and gl,,v (gl,,v was obtained from Tuleen who reported its location on chromosome 4 (1970). The current map of chromosome 4 would be:
