“…A band to band analysis showed many similarities. The central part of the X chromosome is conserved in comparison to the cattle X chromosome as already noted for goat, cattle and sheep X chromosomes (HAYES et al 1991). The Y chromosome is acrocentric and smaller than the cattle submetacentric Y chromosome and shows several light positive bands.…”

“…Chromosomes were prepared from blood lymphocytes and skin cell cultures (CRIBIU et al 1990). GTG-bands were obtained according to a modified technique of SEABRIGHT ( 1971), CBG-banding followed the barium hydroxide/saline/Giemsa ( BSG) technique ( SUMNER 1972), and RBG-banding, the technique of VIEGAS-PEQUIGNOT et al (1989) andHAYES et al (1991). Banded chromosomes were arranged according to the standardized cattle karyotypes of ISCNDA 89.…”

Karyotypes of five males and one female scimitar-horned oryx (Oryx dammah) were prepared using lymphocyte and skin cells. CBG-, GTG-, and RBG-banded chromosomes were analysed and the banding patterns were compared with those of cattle, revealing a high level of homoeology except for chromosomes 9, 14, 21, Y, and X. Standard karyotypes are proposed for the scimitar-horned oryx karyotype, which contains 58 chromosomes with one pair of large submetacentric autosomes and 27 acrocentric autosomal pairs. The X and Y chromosomes are the largest and smallest acrocentrics. The scimitar-horned oryx chromosome 1 is submetacentric and appears to result from the fusion between ancestral forms of bovid chromosomes numbered 1 and 29 according to the READING CONFERENCE (1980) nomenclature and to ISCNDA 89 if GTG-banding is used.

The karyotype of the addax (Addax nasomaculatus, 2n = 58) has been investigated by RBG and CBG banding techniques. All chromosomes are acrocentric except the first pair of autosomes, which is submetacentric. The X chromosome is the largest acrocentric, and the Y chromosome is a medium sized acrocentric. According to the standard conventions used for cattle and goat, p- and q-arms of the pair of submetacentric autosomes correspond, respectively, to chromosomes # 27 # 1. The comparison of banding patterns of chromosomes in addax and four other species of the subfamily Hippotraginae reveals several common features and a high degree of homoeology with caprine and bovine karyotypes.
