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 :-
