Primary spermatocytes are diploid (2n) cells with all of the organelles typically found in eukaryotic animal cells. Spermatogenesis begins with a primary spermatocyte with 6 chromosomes, which undergoes meiosis 1 to produce two secondary spermatocytes with 3 chromosomes in each. Each of the secondary spermatocytes undergoes meiosis 2 to produce 2 spermatids, with 3 chromosomes in each. The 4 spermatids mature into spermatozoa.
(a) Describe the process in meiosis that ensures that both maternal and paternal chromosomes are passed on to each spermatozoon.
(b) Explain why the genetic content of individual chromosomes in a spermatozoon most likely differs from the genetic content of individual chromosomes in a primary spermatocyte.
(c) In some instances, meiosis of a primary spermatocyte with six chromosomes results in two spermatozoa that contain four chromosomes and two spermatozoa that contain two chromosomes. Predict the most likely cause.
