Sexual reproduction in humans … At fertilization, 23 chromosomes are donated by each parent. (total = 46 or 23 pairs). Gametes (sperm/ova): Contain 22 autosomes and 1 sex chromosome. Are haploid (haploid number “n” = 23 in humans ). Fertilization results in diploid zygote. Diploid cell; 2n = 46 . ( n = 23 in humans ) Most cells in the body are produced through _________ . Only gametes are produced through _________. Image: Superficial human anatomy , Mikael Häggström& Rainer Zenz; Sperm & egg , Wikipedia From the Virtual Cell Biology Classroom on ScienceProfOnline.com

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
