Abstract:
We consider a class of models for the evolution of a DNA sequence that allows for interaction among neighbouring elements. When the evolutionary distance between two sequences is small the number of changes along the sequence will be small. Categorizing the changes we prove a multivariate Poisson approximation to the distribution of the number of changes.
