We consider a Moran model describing the evolution of a population of size $m$ of chromosomes of length $\\ell$ over an alphabet of cardinality $\\kappa$. The mutation probability per locus is $q$. We deal only with the sharp peak landscape: the replication rate is $\\sigma>1$ for the master sequence and 1 for the other sequences. We study the equilibrium distribution of the process in the regime where $\\ell, m\\to +\\infty$, $q\\to 0$, $\\ell q \\to a$, $m/\\ell\\to\\alpha$.
