 Remarks
 NF = 104-106 (Ref. 10366). 2n = 60 (Ref. 13141). 2n = 60-62 (Ref. 8973). 2n = 58 (Kamloops Lake region) (Ref. 27392). 2n = 60, 62, NF = 108, CF = 48, 46m + 12, 16a; 2n = 50, 60, NF = 104, CF = 46, 44m + 12, 16a ; 2n = 59-63, NF = 104, CF = 41-45m + 14-22a (Ref. 27416). Most common sex determining mechanism is XY for males (heterogametic) and XX for females (homogametic). Presence of heteromorphic sex chromosomes in male reported (Ref. 9943). Also Ref. 12619 and 12795.
