Question

How many secondary spermatocytes are produced from one primary spermatocyte during Meiosis I?

Options

• One Secondary Spermatocyte with 46 chromosomes

• Four Secondary Spermatocytes, each haploid with 23 chromosomes

• Two Secondary Spermatocytes, each haploid with 23 chromosomes

• Two Secondary Spermatocytes, each diploid with 46 chromosomes

Answer 1

During Meiosis I (the first maturation or reduction division), each Primary Spermatocyte (2n, 46 chromosomes) undergoes division to produce two Secondary Spermatocytes, each haploid (n) with 23 chromosomes. This division is where the critical ploidy reduction occurs, converting diploid cells to haploid cells.
