4. The production of spermatozoa, through the process of spermatogenesis, starts out with a spermatogonium that undergoes several successive divisions. In fact, from spermatogonium to spermatozoa, three mitoses and one meiosis take place. Use a flow chart to answer the following questions:
a. Identify the different steps of spermatogenesis including spermatogonium, spermatogonia, primary spermatocytes, secondary spermatocytes, spermatids, and spermatozoa.
b. Which cells are diploid? Which cells are haploid?
c. How many spermatozoa are produced from a single spermatogonium?
