Simulation – Evolution of the number of genes
I would like to simulate the evolution of the number of genes along a phylogeny (Under a BM or OU model), following a birth-and-death model. I would like to use a real species tree, and two parameters : a mean birth rate of genes and a mean death rate of genes.
Do you have any idea of program or R package (or python) that would be suitable to perform this kind of simulation ?
Thanks a lot for any help provided !
