He parental RC phenotype; or (iii) the causative mutation could possibly be semidominant; however, this alternative would imply a really low penetrance in the allele. The variations involving the observed and anticipated frequencies might be because of the size on the population used for this evaluation. Thus, we couldn’t distinguish between the alternatives (i) and (ii). This limitation could potentially be solved by escalating the population size chosen for the screening. Though (iii) is feasible, the penetrance would have to be significantly low for the causative mutation to be dominant, making this option hugely unlikely. In such a case, the 
only distinction involving a single recessive as well as a semidominant mutation will be the phenotype with the heterozygote animals; in the first situation they would possess a phenotype comparable to the DA parental strain, and within the second, an intermediate phenotype would be expected involving the two parental strains. Even though we observed intermediate phenotypes throughout screening, these were most likely because of the intrinsic variability of the assay. The use of this WGS-SNP mapping strategy (Doitsidou et al. ; Minevich et al.) permitted us to figure out that the resistance to P. aeruginosa infection in strain RC maps to a .-Mb area involving positions ,, and ,, on chromosome V.

This larger region of chromosome V with reduce recombination frequencies may be due to the population size made use of for this study, or towards the enhanced resistance of RC to P. aeruginosa infection resulting from a potentially complex trait of two or much more loci on chromosome V. Inside the .-Mb mapping interval, genes harbored a SNP in between the RC and DA strains. To decide when the loss of function of any of those genes was PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/24709813?dopt=Abstract responsible for the enhanced resistance to P. aeruginosa infection phenotype, we knocked them down systemically by RNAi. No difference was observed in between the RNAi therapies compared using the handle situation, indicating that the loss of function of these genes is not responsible for the enhanced resistance to pathogen infection, at least systemically.

Hence, we could not distinguish among the options (i) and (ii). This limitation could potentially be solved by rising the population size chosen for the screening. Though (iii) is feasible, the penetrance would need to be considerably low for the causative mutation to be dominant, generating this solution highly unlikely. In such a case, the only distinction between a single recessive and also a semidominant mutation would be the phenotype on the heterozygote animals; in the very first predicament they would possess a phenotype related for the DA parental strain, and in the second, an intermediate phenotype will be expected between the two parental strains.
