  Some population is made of n individuals that can be of p possible species
(or types). The update of the species abundance occupancies is from a Moran
mutational model designed by Karlin and McGregor in 1967. We first study the
equilibrium species counts as a function of n, p and the total mutation
probability $\nu$ before considering various asymptotic regimes on n, p and
$\nu$. Running title: KMG Model with Mutations.
