Umblachery breed is an excellent draught cattle of Tamilnadu, noted for its strength and sturdiness especially used in the marshy fields for wed ploughing. Several genetic markers have been used for identification of farm animals. The present study was undertaken to characterize the Umblachery breed with chromosomes. The diploid chromosome number in Umblachery cattle was 2n=60 comprising of 29 pairs of autosomes and one pair of sex chromosomes. All autosomes are acrocentric, the X- chromosome is submetacentric and Y chromosome is acrocentric. C-banding in Umblachery cattle was showed all autosomes with darkly stained centromere but the sex chromosomes were found to be C-band negative.Keywords

Java programming is popular both in Academia and IT Industry. Further, it is the maximum usage of programming across the world. There is a wide edge between industry expectations and knowledge of students in Java programming. Teaching and learning of Java programming in academia is the greater responsibility to shrink that edge. The present study has been conducted in this regard to investigate the factors that lead to students' learning difficulties in Object-Oriented Programming Paradigm using Java. The result of this study indicates that the students have learning difficulties on the topics of Java programming. The nature of difficulties, situations and the various factors that lead to poor performance in learning of Java programming were also identified.Keywords
