reproductive system
• macroscopic evaluation of testis and epididymis revealed no difference in morphology, size or weight
• no difference in the diploid cells or haploid cells population distribution of testicular cells
• the long tails of spermatozoa were completely absent in the lumen of the seminiferous tubules
|
• males were unable to produce offspring when crossed with wild-type females
• reproductive behavior and production of copulatory plugs are normal
