Abstract

Events in oogenesis, fertilization, and the first cleavage division of Dicyema aegira are interpreted as occurring, usually, in the customary manner. Two polar bodies are formed, with reduction of the chromosome number to haploid; fertilization occurs; two pronuclei are formed; and the first cleavage division of a diploid zygote is normal.
