(A) OPM-04 RAPD–PCR amplification of genomic DNA from resistant BS-90 (B), susceptible (M) parent snails, and 10 individual resistant progeny. Lane C represents amplification in the absence of template DNA. (B) OPM-04 amplification of DNA from resistant (B) and susceptible (M) parents and 10 individual susceptible progeny. Lane S represents amplification of S. mansoni DNA, and lane C shows amplification without DNA. (C) OPZ-11 amplification of DNA from resistant (B) and susceptible (M) parents and 10 individual resistant progeny. Lane C shows amplification in the absence of template DNA. (D) OPZ-11 amplification of resistant (B) and susceptible (M) parent snail DNA and DNA from 10 individual susceptible progeny. Lane S represents amplification of parasite DNA and lane C shows amplification without DNA.
