Fig. 3From: Female-specific genomic regions and molecular sex identification of the clearhead icefish (Protosalanx hyalocranius)PCR amplification results using PCS primer pair in 48 individuals (12 males and 12 females from Hongze Lake, 10 males and 14 females from Heilong River). The 569Â bp long band (shared by males and females) and the shorter 339Â bp female specific band are indicated respectively. The DL 2000 DNA marker (Sangon Biotech Co., Ltd) is shown in the left.
