How shall this genetic mutation that they are doing induce other genetic mutations in relation to that most femals die and in generall? Or do you meant the virus is mutating for a new host? If not, is there some genetic math that could explaine your point? I am courios :) Edit: because muation is more or less random and is expressed with new generations. So if they die and there is less the chance of mutation or am i wrong??
