L after infusion of 330 ?g/kg of methacholine but not with the other outcome indicators. 3dos; Fig. 4) maps within the region of the linkage previously reported by Ewart et al. (8) on chromosome 6 in the same genetic background, i.e., A/J and C3H/HeJ. The region in which the maximum LOD score was identified on chromosome 6 was contiguous with a region (?27 cM) of recombination suppression noted by us and also previously noted by Ewart et al. The lack of recombinant events was observed in 96 (A/J ? C3H/HeJ) F2 intercross progeny genotyped at these loci and encompassed the following markers:D6Mit243,D6Mitstep step step 101,D6Mit108, andD6Mit366.

The first QTL understood to the chromosome six (top LOD rating = step three

In addition to the significant linkage entirely on chromosome six, linkage has also been imagined to the chromosome seven (LOD = step three.8; Fig.5); new height LOD rating is actually noticed betweenD7Mit21 andD7Mit249. High linkage is provable in the event the a reaction to possibly the latest 330 or 1,100 ?g/kg dose regarding methacholine was applied since phenotypic directory. I tested for hereditary relations within loci playing with simple ANOVA, along with mix-terms for a couple of-way connections. Even in the event all the two loci got a life threatening influence on airway hyperreactivity when establish alone, there’s no proof fun or antagonistic connections impacting airway responsiveness between the QTLs on the chromosomes six and you may eight whenever each other loci was in fact found in the newest backcross progeny.
