Abstract

This thesis deals with the inquiry opened by the fundamental discovery that the gamete nuclei, and hence, the two parents from which they are respectively derived, con­ tribute each a haploid or single group of chromosomes to the fertilized egg. Each act of fertilization doubles the gametic number of chromosomes; yet the number of characteristic of the species remains constant from generation to generation. Somewhere in the life cycle, accordingly, the diploid or somatic number must be reduced by one-half to the haploid or gametic number. The first explanation was that reduction took place by some process of degeneration or casting out of half the number of chromosomes from the nucleus; but subsequent research has shown the process to be very different.
