(A) $T.H. Morgan$ proposed the chromosomal theory of linkage and recombination. He observed that genes located on the same chromosome are linked and that the frequency of recombination between linked genes is directly proportional to the distance between them. Crossing over,which leads to recombination,occurs during the $pachytene$ stage of prophase-$I$ of meiosis,where non-sister chromatids of homologous chromosomes exchange genetic material. Therefore,$T.H. Morgan$ is credited with the development of these concepts.

The theory of recombination of linked genes due to crossing over of chromosomes during the pachytene stage of meiosis was put forward by:
