Abstract
Conclusions
Most of the sperms in the sterile individuals of these genotypes were normal looking and presumably physiologically inefficient. I agree with Chang(10) in stating that a morphologically normal sperm may be physiologically incapable of effecting fertilization. The fact that the acrosome alterations as revealed by P.-A.S. technic may easily be overlooked when treated by usual methods suggests that differences in such non-chromosomal elements may be of considerable importance in evaluating morphological normality of a spermatozoon.
