Abstract
The inheritance of resistance to parathion in the Pacific spider mite was investigated by means of a backcross. A 1:1 ratio of a susceptible and a resistant class indicated the existence of a single dominant gene for resistance.
Since the susceptible parental strain was marked with a recessive for albinism, information was obtained of the genetic relationship between the gene for resistance (R p ) and the gene for albinism (p). The segregation of resistant (R p r p ) and susceptible (r p rp) classes in pigmented (p+p) and albino (pp) animals revealed that there was no linkage between these genes.
