Which of the following statement is incorrect about Hidden Markov Models (HMMs)?

#Section 7: Recombinant DNA technology and Other Tools in Biotechnology
  1. An HMM combines two or more Markov chains with only one chain consisting of observed states and the other chains made up of unobserved (or “hidden”) states.
  2. Unobserved states influence the outcome of the observed states
  3. In an HMM, the probability going from one state to another state is the transition probability.
