SummaryLeukocyte and skin cultures of a female hybrid between a donkey and Grevy zebra show a diploid chromosome complement of 48. From this finding it is inferred that the Grevy zebra is characterized by 2n=34 and that such hybrid's regular infertility is analogous to that of mules and hinnies.Barr bodies were present in the tissue-cultured cells and studies with tritiated thymidine show that Barr body and the chromosome set replicate asynchronously. One large element corresponds to the late… 
Vergleich der Chromosomensätze von Steinwild (Capra Ibex) und Hausziege (Capra Hircus)
TLDR
The idiograms of the two species show that the chromosomes 18 to 21 and 41 to 44 differ, but not significantly, from each other, and the observed fertility of the hybrids does not surprise.
Pooling strategy and chromosome painting characterize a living zebroid for the first time
TLDR
A successful new strategy was devised to resolve the difficulty and characterize each chromosome of a living zebra-donkey hybrid, and may have several applications in the resolution of other complex hybrid karyotypes and chromosomal aberrations.
Molecular Cytogenetics of the Equidae: III. Cytological Localization of Heterochromatin and Satellite DNA in Hartmann’s Mountain Zebra, Equus zebra hartmannae (Matschie, 1898)
Zebras have long fascinated zoologists because of their elegant form and striking coloration. Considerable effort has been devoted to analyses of their evolution and systematics. In spite of these
Construction of chromosome-specific paints for meta- and submetacentric autosomes and the sex chromosomes in the horse and their use to detect homologous chromosomal segments in the donkey
TLDR
Examination of the accuracy of the available comparative cytogenetic data between horse and donkey finds that the results not only detected conservation of whole chromosome and/or arm synteny between the two karyotypes, but also highlighted varying degrees of rearrangements.
An autoradiographic study of the chromosomes of the rat, with special regard to the sex chromosomes
TLDR
The pattern of terminal DNA synthesis of rat chromosomes was studied by means of tritiated thymidine incorporation and autoradiography and the relation between the less prominent out-of-phase replication of the late replicating X-chromosome and the difficulty in finding the sex dimorphism of interphase nuclei of the rat is discussed.

Genetic aspects of equids with particular reference to their hybrids
TLDR
A brief review of the cytogenetic knowlege of equine species, the chromosomal errors currently known to exist, and an account of the interspecific hybrids that have served man during the 4500 years of domestication of horse and donkey are given.

TLDR
Dr. Benirschke was born in Glueckstadt, north of Hamburg, where the Holstein cows come from, and finished medical school in Hamburg in 1948 and came to the United States in 1948, where he became number 35 and got a visa to immigrate to America.

Cromosomes of the horse, the donkey, and the mule
TLDR
While the disparity between parental chromosomes satisfactorily accounts for sterility in male hybrids, it does not explain the occasional fertile female able to produce several offspring with no E. asinus traits.
Somatic chromosomes of the horse, the donkey and their hybrids, the mule and the hinny.
TLDR
There exist structural differences which are most noticeable in greater numbers of metacentric chromosomes in the donkey, and it is possible that these physical differences play a role in synaptic failure during meiosis.
