hybridization studies of one of these unusual strains with 32p-labelled mrnas derived from the prototype human strains wa ( serotype 1 , subgroup ii ) and s2 ( serotype 2 , subgroup i ) suggested that it was generated by a reassortment event in nature , in which a subgroup ii , 'long ' electropherotype rotavirus exchanged its serotype-specific gene and gene number 10 for the equivalent genes from a serotype 2 , 'short ' electropherotype virus .
