From: A unique 15-bp InDel in the first intron of BMPR1B regulates its expression in Taihu pigs
Identification of the 15-bp insertion sequence in the first intron of BMPR1B from four pig breeds. a Electropherograms generated by sequencing the BMPR1B InDel loci. Black arrowhead: variant sites; Red boxes indicate insertion sequences. Bases in red indicate that the InDel was present on only one chromosome. b Image of stained polyacrylamide gel. The image at the bottom is a magnified view of the area enclosed by the yellow box. The two thin horizontal yellow lines indicate the 238 bp marker (upper line) and the 217 bp marker (lower). In the magnified region, downward pointing arrows indicate bands containing the 15-bp InDel in hybrid pigs, while upward arrows indicate band that do not contain the InDel in hybrid pigs. “A” indicates presumptive heteroduplex.
