Fig. 1. DNA electrophoretic patterns obtained after digestion with AluI endonuclease of the DNA region containing the sixth exon of the goat
POU1F1 gene; (Lane M) DNA Marker (Tianwei times, China); (Lane 1) CC genotype (216, 124 and 110 bp); (Lanes 2, 4 and 5) TT genotype (340
and 110 bp); (Lane 3) TC genotype (340, 216, 124 and 110 bp); (Note: as it is difficult to classify the 124 and 110 bp on 2% agarose gel, CC and TC
genotypes showed two or three invisible fragments. It is obvious that 340 and 216 bp fragments could clearly classify the genotypes).
