Identification of heterosomes in spermatoza of rams with 54,XX/54,XY chimerism

The aim of the study was to identify heterosomes in the semen of three Romanov rams – carriers of leukocyte chimerism (FISH technique) and to determine the proportions between spermatozoa with X and Y chromosomes. The choice of bovine probes for hybridization with ram heterosomes was dictated by genetic conservatism of bovine and ovine heterosomes. The ratio between spermatozoa with a yellow fl...

The leukocyte culture method in the diagnosis of freemartinism.

The clinical application and reliability of the leukocyte culture method for the diagnosis of freemartinism were examined and the length of time that blood samples could be held at room temperature and in the refrigerator prior to culturing, was investigated. The chromosome findings by the leukocyte culture method in 14 freemartins and 9 non-freemartin females belonging to heterosexual twins or...
