Vedclass · Answer

(C) In $Drosophila$ (fruit fly),crossing over is a process that occurs during the pachytene stage of prophase-$I$ of meiosis. It is a well-established biological fact that crossing over is completely absent in male $Drosophila$. Due to the absence of crossing over in males,linked genes do not undergo recombination,and they are inherited together as a single unit. Therefore,the correct explanation for the lack of recombination in male $Drosophila$ is that crossing over does not occur in them.

In female $Drosophila$,linked genes show recombination during meiosis. However,such recombination does not occur during sperm formation in male $Drosophila$. Why?
