Sister chromatid exchange analysis in some Holstein bulls %K Sister chromatid exchange %K Bull %K Bromodeoxyuridine %R 10.22099/ijvr.2012.119 %X Chromosomal appearance of 12 Holstein bulls selected for artificial inseminations were examined bysister chromatid exchanges (SCEs). For differential staining of sister chromatids bromodeoxyuridine (BrdU)was inoculated in lymphocyte cultures. The mean, maximum and minimum number of SCE per cell weredetermined 6.8 ± 1.14, 8.3 ± 1.1 and 5.7 ± 1.5, respectively. SCE frequencies of all animals were in thenormal level. Also, evaluation of different breeding condition and age range did not show any significantstatistical (P>0.05) effect on SCEs rates %U https://ijvr.shirazu.ac.ir/article_119_e9b634869658acabaf1d1a2ea76c5f42.pdf
