F1 crosses between B6 and 129. F1 progeny were generated in three different crosses. (A) An NPcis-B6 male was bred to a WT 129 female to give NPcis-B6X129 F1 progeny that were resistant to astrocytoma. (B) NPcis-129 females were bred to WT B6 males to give NPcis-129XB6 F1 progeny that were susceptible to astrocytoma. (C)An NPcis-129 male was bred to a WT B6 female to give NPcis-129XB6 F1 progeny that developed an intermediate astrocytoma phenotype.
