“…Furthermore, the survival rate of hybrid embryos decreased gradually thereafter: 21% embryos survived at 5 days, 15% at 10 days, and 14% at 12 days. There was large variation in fertilization and survival rates between individual female quail, which concurs with previous studies (Haley et al, 1966;Takashima and Mizuma, 1981). Therefore, fertilization and survival rates are likely to fluctuate across studies.…”

Hybrid incompatibility is important in speciation as it prevents gene flow between closely related populations. Reduced fitness from hybrid incompatibility may also reinforce prezygotic reproductive isolation between sympatric populations. However, the genetic and developmental basis of hybrid incompatibility in higher vertebrates remains poorly understood. Mammals and birds, both amniotes, have similar developmental processes, but marked differences in development such as the XY/ZW sex determination systems and the presence or absence of genomic imprinting. Here, we review the sterile phenotype of hybrids between the Phodopus dwarf hamsters P. campbelli and P. sungorus, and the inviable phenotype of hybrids between two birds of the family Phasianidae, chicken (Gallus gallus domesticus) and Japanese quail (Coturnix japonica). We propose hypotheses for developmental defects that are associated with these hybrid incompatibilities. In addition, we discuss the genetic and developmental basis for these defects in conjunction with recent findings from mouse and avian models of genetics, reproductive biology and genomics. We suggest that these hybrids are ideal animal models for studying the genetic and developmental basis of hybrid incompatibility in amniotes.

“…Preliminary evidence for the existence of such an immunological mechanism causing reduced inter-376 L. E. Haley and H. Abplanalp specific fertility was found in a selection experiment where quail [Coturnix coturnix japónica) hens were routinely tested for their ability to produce hybrids when inseminated with fowl {Gallus domesticus) semen (Haley, Abplanalp & Enya, 1966;Haley, 1967 Experimental inseminations in Groups I and II were begun when the quail hens were 22 weeks old, 7 weeks after the preliminary fertility tests were dis¬ continued. In Group III, the lapse in inseminations after preliminary tests lasted 13 weeks, until the hens were 28 weeks old.…”

Summary. Female quail from populations selected for high interspecific fertility when bred with fowl were inseminated half-weekly with fowl semen for periods up to 18 consecutive weeks. At the end of that time, all birds showed a decline in interspecific fertility and the blood plasma of approximately half of the female quail contained antibodies against fowl spermatozoa. The interspecific fertility of these birds was considerably less than that of the birds which did not have antibodies.In a second experiment, female quail with high interspecific fertility were given an intravenous injection of fowl semen. Their interspecific fertility was approximately 10% lower than a control group of female quail.

“…The fertilization rate in the interspecific crosses is low, ranging from 5.4 to 25.3% 33 34 35 36 37 38 . The fertilization rate is largely different among breeds of chickens and quail strains used for hybridization 33 37 39 . In most fertilized eggs, embryonic development is arrested around the formation of the extraembryonic membrane and/or blood islands, and in a small fraction of the remaining fertilized eggs, hybrids are hatched 37 .…”

Interspecific hybrid incompatibility, including inviability and sterility, is important in speciation; however, its genetic basis remains largely unknown in vertebrates. Crosses between male chickens and female Japanese quails using artificial insemination can generate intergeneric hybrids; however, the hatching rate is low, and hatched hybrids are only sterile males. Hybrid development is arrested frequently during the early embryonic stages, and the sex ratio of living embryos is male-biased. However, the development and sex ratio of hybrid embryos have not been comprehensively analyzed. In the present study, we observed delayed embryonic development of chicken-quail hybrids during the early stage, compared with that of chickens and quails. The survival rate of hybrids decreased markedly during the blastoderm-to-pre-circulation stage and then decreased gradually through the subsequent stages. Hybrid females were observed at more than 10 d of incubation; however, the sex ratio of hybrids became male-biased from 10 d of incubation. Severely malformed embryos were observed frequently in hybrids. These results suggest that developmental arrest occurs at various stages in hybrid embryos, including a sexually non-biased arrest during the early stage and a female-biased arrest during the late stage. We discuss the genetic basis for hybrid inviability and its sex bias.
