Backcrossing approach to introgress ivermectin resistance-conferring genes from resistance strains into the MHco3(ISE) genetic background.

<p>Diagrammatic representation of overall backcrossing scheme (A). Schematic representation of experimental aim and summary of nomenclature used (B). Genome of the MHco4(WRS) ivermectin resistant strain represented in red and the genome of the MHco3(ISE) susceptible reference strain represented in blue.
