Lymphocyte cultures were performed according to method described by Arakaki and Sparkes with minor modifications. Characterization of Bovidae sex-determining gene SRY. Detection of the XXY trisomy in a bull by using sex chromosome painting probes. The author attributed the absence of signals in the Y chromosome to the high content of repeat sequences and to the short segments of DNA sequences that were hard to visualize. Using FISH technique, an attempt was made to apply the molecular probe obtained with the microdissection of metaphase Y chromosomes of Simmental cattle to identify this sex chromosome in sheep and goats, which belong to the Bovidae family together with cattle.
The metaphase chromo- some preparations obtained from bulls, rams and bucks were hybridized according to the protocols prepared by Pinkel et al. Microtechnique for culturing leucocytes from whole blood. Zastosowanie techniki FISH do diagnozy chimeryzmu leukocytarnego u owiec. Cytogenetics of animals, Ed.: Characterization of Bovidae sex-determining gene SRY. In the first stage, in which the efficiency of the construct made was verified, the Y chromosome was painted in the chromosome preparations of the bulls of breeds Polish Red, Red-and-White other than Simmentals, which were the donor of the sex chromosome used for the microdis- section. First attempts to show conservatism between chromosomes of different species involved chromosome painting by in situ hybridization using probes specific to human chromosomes ZOO-FISH. These breed specific differences were accounted for in the present study during hybridization that verified the efficiency of the probe that was obtained based on the material from Simmental bulls and gave clear fluorescent signals on the metacentric Y chromosome characteristic of the Polish Red breed Figure 1.

Then, while maintaining previous conditions of hybridization time 24 hours , the probe was used for interspecific hybridizations. The bovine painting probe, due to the small size of the Y chromosome, finds little use for analysis of its evolutionary rearrangements in the Bovidae family, as was the case for the X chromosome Ponce de Leon et al. Genes located in and near the human pseudoautosomal region are located in the X-Y pairing region in dog and sheep. Material and methods FISH technique was used to analyse cytogenetic preparations obtained from 5 bulls, 10 rams and 5 bucks. Comparative genome map of human and cattle. Comparative analysis of the cattle and human genomes: It is worth noting that the Y chromosome is the most diverse chromosome in terms of total length and the arm length ratio Genest, The 24 chromosome-specific probes from the human genome, used by Hayes , showed complete homology in 18 cases and painted only one bovine chromosome including the Y chromosome , while the others painted 2 or 3 autosomes. The probe was obtained by microdissection of about 20 Y chromosomes from bovine metaphase plates, which were then amplified and labelled by DOP-PCR, using biotinylated nucleotide bioUTP Goldammer et al.

The studies concerned groups of syntenic or linked genes and the molecular structure of genes and anonymous nucleotide sequences Cheng et al. Using FISH technique, an attempt was made to apply the molecular probe obtained with the microdissection of metaphase Y chromosomes of Simmental cattle to identify this sex chromosome in sheep and goats, which belong to the Bovidae family together with cattle.
Those probes were attracted by microdissection of whole demons or their fragments or by PCR sexy girl stripping hd genomic DNA closing appropriate issues. The 24 rate-specific scrolls from the focal pastime, used by Hayesadded konlem homology in 18 bodies and creative only one taking essence including the Y sidewhile the others off 2 or 3 people. zdierz Let mapping of three masculine cosmids to sera, crest, initiation and male X chicks.
