A scientist performed the gene mapping experiments in maize. He mapped the gene on chromosomes on the basis of % crossing over between different genes. One map unit corresponds to one % crossing over or recombination. Te genes showing more than 50% recombination were not supposed to be linked on same chromosome. In crossing over studies on maize, scientist observed the following % crossing over between A B, C, d- between. A and D 10% between A and C 3% between genes C and D 7% between genes A and B 5% , and between genes C and B 8% on the basis of above observation find out the correct sequence of tenes Alt B, C, and D on chromosomes :-
