Which of the following pairs of cells represents the immediate haploid products formed by the completion of the first meiotic division during gametogenesis?

Step-by-step solution

During gametogenesis, the diploid primary spermatocytes and primary oocytes undergo the first meiotic division (Meiosis I). In males, the primary spermatocyte completes the first meiotic division leading to the formation of two equal, haploid cells called secondary spermatocytes. In females, the primary oocyte completes the first meiotic division to form a large haploid secondary oocyte and a tiny first polar body. Therefore, the secondary spermatocyte and secondary oocyte are the immediate haploid products of Meio
