[The "hitch-hiking" effect of a selected gene and gamete combination (linkage disequilibrium): the example of 2 closely linked loci in the swine, Hal (halothane sensitivity) and PHI (phosphohexose isomerase)].
The observation of two lines of pigs selected differently for four generations confirms a recent theoretical work (Thomson, 1977) showing that a possible source of linkage disequilibrium may be the hitch-hiking effect of a selected locus (Hal) on another closely linked neutral locus (PHI).
