Title:Stochastic gene expression in switching environments
View PDFAbstract: We study a stochastic model proposed recently in the genetic literature to explain the heterogeneity of cell populations or of gene products. Cells are located in two colonies, whose sizes fluctuate as birth and migration processes in switching environments. We prove that there is a range of parameters where heterogeneity induces a larger mean fitness
