it is concluded that both the production of protamines and protamine cross linking by s-s bridge formation are rather autonomous processes during spermatogenesis because 1 ) the increased dna variance of the aneuploid spermatozoa is not reflected in an increased variance of the total and free sh-groups , 2 ) aneuploidy for the protamine gene carrying chromosome 16 is not reflected by the sh-group values for individual spermatozoa , and 3 ) protamine production and cross linking are independent of the mild to severe terataspermiogenesis in the tertiary trisomic karyotype .
