Circadian clock gene ( Ots Clock1b) variation and time of ocean return in Atlantic salmon Salmo salar.

The article discusses the study which investigates the significant connection between genetic variation at circadian clock gene (OtsClock1b) and run-time phenotype in Atlantic salmon. Topics discussed include microsatellites variability, genetic drift, and fish population. The study found that there is a significant connection between OtsClock1b variation and Atlantic salmon or Salmo salar L.
