Figure 1

Interval mapping of QTL on chromosome GGA1. Only the three traits with QTL detected on GGA1 are shown: WG (Body Weight Gain), PC (Plasma Coloration) and HEMA (Hematocrit level). Variance ratios (F) are shown for the different models used to identify the QTL: a&d (additive and dominance effects), a (additive effect) and i (parent of origin effect). For example, BW_a&d represents the Body Weight Gain trait using an additive and dominance effect model. Positions of the markers are indicated by black lozenges and flanking markers of the QTL identified (pointed by an arrow) are indicated by grey lozenges. Corresponding significance levels of the QTL are given in Table 4.
