Characterization of the atlantic salmon sex-determining chromosome
I have integrated data from linkage mapping, physical mapping and karyotyping in order to characterize the sex chromosomes in Atlantic salmon (Salmo salar). The primary genetic sex-determing signal, SEX, has been mapped to Atlantic salmon microsatellite linkage group 1 (ASLI). I have used probes des...
