Figure 2.

A graphic illustration of the estimated QTL effects on fatness traits for 10 backcross sires from a wild boar/Large White intercross. The x-axis represents Δ average subcutaneous fat and the y-axis represents Δ average abdominal fat (in both cases wild/domestic heterozygotes – domestic homozygotes). Boars represented by a black circle or a rectangle were deduced to be heterozygous or homozygous, respectively, at FAT1, whereas the QTL data were inconclusive for boars represented by a white circle. BCXy: BCX = backcross generation X, y = pig identity number.
