“…Triploidy occurs in up to 3.3% of chicken embryos and is a known cause of embryo mortality in birds [Forstmeier and Ellegren, 2010]. In domestic chickens, spontaneous triploidy is well documented [de Boer et al, 1984;Bonaminio and Fechheimer, 1993] with viable, but infertile ZZZ and ZZW gonosomal types. Lin et al [1995] reported that ZZZ birds have irregular meiosis and produce abnormal spermatozoa, but the behavior of chromosomes during meiosis was not described.…”

The cytological analysis of meiotic chromosomes is an exceptional tool to approach complex processes such as synapsis and recombination during the division. Chromosome studies of meiosis have been especially valuable in birds, where naturally occurring mutants or experimental knock-out animals are not available to fully investigate the basic mechanisms of major meiotic events. This review highlights the main contributions of synaptonemal complex and lampbrush chromosome research to the current knowledge of avian meiosis, with special emphasis on the organization of chromosomes during prophase I, the impact of chromosome rearrangements during meiosis, and distinctive features of the ZW pair.

“…Two diploid-triploid chickens have been reported pre viously (Abdel-Hameed and Sholfncr. 1971;De Boer et al, 1984), and viable diploid-triploids have been found in turtles (Bickham et al, 1985), fish (Murayama et al, 1986), and mammals, including man (Gra ham et al, 1981) 1973), and mink (Fechheimer et al. 1983).…”

Sixteen haploid-diploid chickens, four diploid-triploids, and one haploid-diploid-triploid chicken have been found in a layer line of crossbred origin. Live haploid-euploid vertebrates have not been reported previously. Flow cytometric analysis revealed 1–80% haploid red blood cells (RBCs) in the haploid-euploid chickens and 5–30% triploid RBCs in the diploid-triploids. Mosaic cell lines were also found in leukocytes and many tissues. The haploid-diploid chickens were all phenotypically normal and fertile, but the phenotype and fertility of the diploid-triploid chickens depended on their sex-chromosome complements and the ratio of diploid to triploid cells. The haploid cell lines are thought to originate from supernumerary spermatozoa, and the diploid-triploids from binucleated oocytes with meiotic errors. It is likely that genetic factors are partly responsible for the occurrence of these mosaic chickens.

“…When the incidence of male gonads within a treatment group was too low, this treatment was repeated in another experiment. Karyotyping was performed as described by De Boer et al (1984), using the remaining soft tissues of the embryos. In the experiment in which morphometric measurements were also made, the histology procedure was the same as that described for the in vitro reaggregation culture.…”

Daudi supernatant, unlike other H-Y antigen sources, exerts a sex-reversing effect on embryonic chick gonad differentiation

In vitro cultures of intact chick gonads (organ cultures) and reaggregation cultures of dispersed gonad cells (roller cultures) were made. Gonads or gonad cells from 7-day-old chick embryos, at the stage when sex-specific differentiation begins, were cultured in the presence of presumed H-Y antigen-containing supernatants, or co-cultured in the presence of H-Y antigen-producing cell lines. The H-Y antigen-producing cells tested were of human, mouse, bovine and chicken origin. During organ culture, addition of supernatant of the human lymphoma cell line Daudi, or co-culture with Daudi cells, stimulated a clear proliferation of the germinal epithelium in male gonads, indicating feminization. A similar effect was obtained by treatment with estradiol. In reaggregation culture, the increase in nuclear size of germ cells was chosen as a parameter for feminization. A significant increase of germ cell nuclear size was observed in gonads cultured in the presence of Daudi supernatant. In both organ cultures and reaggregation cultures, other tested H-Y antigen sources and semi-purified H-Y antigen fractions did not exert significant effects on differentiation of the gonads or on the average area of the germ cell nuclei. These findings suggest that it is not H-Y antigen, but another protein produced by Daudi cells, that might be responsible for the sex-reversing effects.
