Survival probabilities for some multitype branching processes in genetics

  • Edward Pollak


Consider a positively regular, slightly supercritical branching process withK types. An approximation to the probability of survival of a line descended from a single individual of typei has recently been derived by Hoppe. IfK is large, however, this approximation may not be easy to compute. A further approximation that is easily computable is given. The result is used to estimate probabilities of survival of an allele A that is originally present in one male or one female in a large, random mating, age-structured population. Both autosomal and sex-linked loci are considered. Another application of the approximation is also discussed.
