    E. 0.0.

    Explanation:

    The measure of crossing over coincidence interrelatedness between one cross over and another in a given pair of chromosome is known as what is called Interference.

    Given that:

    the interference value = 1

    The probability of recombination between genes A and B is zero i. e 0.0 because:

    when another gene co-occur with a particular gene during cross over, the coefficient of coincidence decreases. We know that the interference is maximum at 1, we can say it ranges from 0-1; now that two recombination is taking place in two genes, the probability is likely to decrease from 1 to 0.0

    Similarly; Since the probability of recombination is taking place between two genes i. e genes A and B. Then there is no probability of double crossover when interference value = 1 but when it is zero there is probability of double crossover to occur. With that being said, the probability of recombination between genes A and B is 0.0
