We study Markov symmetrical and nonsymmetrical random evolutions in 𝐑𝑛. Weak convergence of Markov symmetrical random evolution to Wiener process and of Markov non-symmetrical random evolution to a diffusion process with drift is proved using problems of singular perturbation for the generators of evolutions. Relative compactness in πƒπ‘π‘›Γ—Ξ˜[0,∞) of the families of Markov random evolutions is also shown.
