Study of the human male meiosis

Abstract
Results obtained from a meiotic study of 250 pachytene cells from four normal human males are presented. G-banding patterns for pachytene bivalents, obtained using trypsin treatment, are also presented; a comparative study between G-banding patterns of pachytene bivalents and G-banding patterns of mitotic chromosomes, and a study of chromomere counting and distribution, have also been made.
