Abstract

In the parthenogenetic egg destined to produce a 9 the number of chromosomes is 22, as in the sexual egg; the reduced number in the latter is 11. No reduction occurs in the parthenogenetic egg. Parthenogenetic eggs destined (in all probability) to produce d" have approximately 22 chromosomes, the exact number not determined. The exceptional nuclear substance which stains as does chromatin, but which is not chromatin, is discussed in connection with the chromosomes.
