 Remarks
 n=20 (Ref. 21). The chromosome length varies between 3.76% and 12.01% (Ref. 8979). DNA value (haploid) = 0.95 (Ref. 8979), 0.99 (Ref. 12384). DNA fingerprinting used in identification and management (Ref. 9238). Males homogametic and females are heterogametic (Ref. 3595). Heterogeneous haemoglobin phenotypes observed through isoelectric focusing (Ref. 33339). Also Ref. 12786.
