Vedclass · Answer

(C) Crossing over is a biological process that occurs during meiosis $I$ (prophase $I$) where homologous chromosomes exchange genetic material. In $Drosophila$ (fruit fly),crossing over is completely absent in males. This is a well-documented genetic phenomenon where the male $Drosophila$ does not exhibit recombination between homologous chromosomes during spermatogenesis. Therefore,the correct answer is the male $Drosophila$ fly.

In which of the following is the phenomenon of crossing over $NOT$ observed?
