Abstract

The farm animals Sheep (Ovis aries 2n=54; Slovak Merino Breed) and cattle (Cow, Bos taurus 2n=60; Cross Breed Holstein-Friesion) have been studied in order to evaluate cytogenetic suitability of their respective breed for future breeding programme. We have encountered several chromosomal aberrations in the sheep as well as in Cow. Sheep, besides acrocentric fusions, chromatid deletions show dicentric chromosomes and premature centromeric divisions. These are indicative of sterility. Similarly, cow genome is characterised by prepondrance of Robertsonian translocation involving chromosome 1/29, differences in X chromosome (Metacentric/Submetacentric) and centric fusions giving a aneusomatic counts 2n = 58-59, instead of 2n=60.

 

Keywords: Sheep breeding, cow breeding, Chromosomal inconstancy, Robertsonian translocation
