What is the end result of spermatogenesis?

The end result of spermatogenesis is four sperm cells, each with half of the original number of chromosomes. This process involves meiosis, where a diploid germ cell undergoes two rounds of cell division. The first division reduces the chromosome number by half, creating two haploid cells. These two haploid cells then undergo a second division, resulting in a total of four haploid sperm cells, each genetically distinct due to recombination and independent assortment. This halving of chromosome number is crucial for sexual reproduction, as it ensures that when a sperm fertilizes an egg, the resulting zygote will have the correct diploid number of chromosomes. The other options do not accurately represent the outcome of spermatogenesis.
