Sheep gene mapping: assignment of ALDOB, CYP19, WT and SOX2 by somatic cell hybrid analysis

Twenty‐four hamster‐sheep hybrid cell lines representing eleven ovine synteny groups were used to make syntenic assignments for seven loci ALDOB (aldolase B, fructose biphosphate); AMH (anti‐Müllerian hormone); CYP19 [cytochrome P450 aromatase, subfamily XIX (aromatization of androgens)]; WT (Wilms' tumour gene); SOX2 (SRY‐related HMG‐box gene 2); FSHB (follicle‐stimulating hormone, beta polypeptide); and SRY (sex region of Y chromosome). These loci were assigned to synteny groups U11(chr2) (ALDOB); U19 (AMH); U3(chr7) (CYP19); and to chromosomes 15 (WT) and 1 (SOX2). SRY defines the hybrids containing the Y chromosome. © 1995 International Society for Animal Genetics
