antimorphic allele - genetic evidence
Permissive for sigma virus multiplication. CO2 sensitive.
Permits infection by the rhabovirus sigma.
permissive or normal allele
Frequency of ref(2)Pp allele compared to that of ref(2)Po did not change during time course of study of sigma virus Type I and Type II frequencies.
ref(2)Po and ref(2)Pn are the most frequent alleles found in nature in Europe.
Permissive (susceptible) line to the sigma virus, determined by a CO2 sensitivity assay.
