In 1930 Sergey L. Sobolev [6, 7] has proposed a construction of the solution of the Cauchy problem for the hyperbolic equation of the second order with variable coeffi cients in 3-d. Although Sobolev did not construct the fundamental solution, his construction was modified in 1986 by Romanov [4] to obtain that solution. However, these works impose a restrictive assumption of the regularity of g...

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...
