How is a sperm cells nucleus different
WebThe nucleus of the human sperm cell is haploid which means that it contains only 23 chromosomes. The chromatin fibers present in the nucleus are densely coiled. During the fertilization process, the nucleus of the sperm cell fuses with the ovum and produces a diploid zygote which then continues to divide and eventually become a complete organism. Web4 mrt. 2024 · Sperm cells swim to and fertilize a female reproductive cell called an oocyte, or egg. Two key factors that can affect male fertility are sperm count and sperm motility. Those...
