Summary Introduction
Introduction:
Virus multiplication is a process in which the infection of viral particles on the host cells. During the infections, it introduces the viral genetic material (DNA or RNA) to the host target cell with the help of some essential proteins. After the infection, it replicates their gene products. The bacteriophage replication is occurs in two ways either lytic or lysogenic cycles.

- You are working in a pathology lab studying the virus Examinaria in mice. You collect the following information about two competing Examinaria strains, Aggressive and Mild: 1. Aggressive always out-competes Mild within a mouse for a payoff of 1. 2. Mild co-exists with Mild in a host for a payoff of 12. 3. Mild always loses to Aggressive for a payoff of 0. 4. Aggressive competing with Aggressive in a host leads to early death of the mouse and a payoff of only 14. Make a payoff matrix to solve this game. Based on the payoff matrix, is there one best Evolutionarily Stable Strategy (ESS) in this game?
