And to find the percent recombination we basically multiply 0.1. So we multiply zero. One times 100% and we get 10% is our percent recombination between those two genes. It basically tells us how many of those offspring are a result of the process of crossing over. Now, we can use this to calculate what the recombination units are or the mapping units. And to basically do that we have to remember that one Map unit or one recombination unit is equal to 1% recombination.
