| Popis: | In a previous, publication (3) the author described the behaviour of the sex-chromosomes, of Dysdercus mendesi Blöte Following conversation with Dr. Luiz O. T. Mendes, the author was simulated to reexamine the, slides and to study another new series of slides" As a result of these observations the¹ writer now concludes that in the division of the 2nd spermatocytes the sex-chromosomes pass undivided to one pole. Thus half of the spermatids receives a single compound element and half receives none. This is believed to be; similar to the conclusions reached by. Dr.. Luiz O. T. Mendes.
