Which of the given features are characteristic of oogenesis but are absent in the process of spermatogenesis? (a) No more gamete mother cells are formed and added after birth (b) The meiotic division is temporarily arrested at the prophase-I stage (c) A single primary gametocyte yields four functional haploid gametes (d) The first meiotic division is unequal, producing a large haploid cell and a tiny polar body (e) T

Step-by-step solution

Statement (a) is a characteristic of oogenesis because oogonia are formed only during embryonic development and no more are added after birth, whereas in spermatogenesis, spermatogonia continue to multiply after puberty. Statement (b) is a characteristic of oogenesis because primary oocytes are arrested at the prophase-I stage of meiosis until puberty, whereas spermatogenesis is a continuous process without such arrest. Statement (c) is incorrect for oogenesis because a single primary oocyte yields only one functio
