Figure 4.

Relationship between female body weight at 70d and litter size based on divergently selected growth lines and an unselected control line (EDC). The means pooled over G4 to 14 are presented. Line description and experimental details are given elsewhere (Bünger et al. 2001b). An ‘i’ indicates inbred, and if shown in brackets, the value comprises data before inbreeding by full-sib matings and from the early inbreeding generations. As there are no obvious inbreeding effects, data from both periods have been pooled. It is of note that inbreeding has accumulated in all selection lines during the selection, but inbreeding in EDC is negligible as it was recently developed from a cross of several control lines.
