    Embryology A. Up to weeks 6–7 of gestation, the early development of organs of reproduction is the same in both sexes.

    B. The paramesonephric (Müllerian) duct degenerates and plays no functional role in the male.

    C. In the male, the distal part of the mesonephric duct becomes greatly elongated and convoluted to form the epididymis.

    D. In the male, the paramesonephric ducts form the vasa deferentia.

    E. In the female, the paramesonephric ducts fuse to form the uterus.

    Q. Spermatogenesis, the process of forming spermatozoa,occurs in the seminiferous tubules. As the cells proceed through the different stages of spermatogenesis, they contain varying numbers of chromosomes and varying amounts of DNA. Spermiogenesis describes a particular stage of spermatogenesis. When the cells are going through spermiogenesis, which of the following is the amount of DNA and the number of chromosomes that exist in those cells?
    (A) 23, 1n
    (B) 23, 2n
    (C) 46, 1n
    (D) 46, 2n
