ArticleItem Open Access Genetic Bottleneck Analyses of Kodi Adu Goat Breed Based on Micro satellite Markers(2015-03) Thiruvenkadan, A.K.; Jayakumar, V.; Saravanan, R.; Kathiravan, P.; TANUVASThesisItem Open Access Genetic evaluation of lifetime performance of sahiwal cattle.(NDRI, Karnal, 2009) Kathiravan, P.; Sachdeva, G.K.ArticleItem Open Access GENETIC VARIABILITY AND BOTTLENECK ANALYSES OF KANNI ADU GOAT POPULATION USING MICROSATELLITE MARKERS(Indian Society for Sheep and Goat Production and Utilization, 2015-10) Jeyakumar, M.; Thiruvenkadan, A.K.; Saravanan, R.; Kathiravan, P.; TANUVASMicrosatellite data on 25 loci were generated and utilized to evaluate the genetic architecture and mutation drift equilibrium of Kanni Adu goats of southern Tamil Nadu. The genetic diversity analysis of Kanni Adu goats displayed higher level of within breed variability in terms of mean number of alleles per locus (11.24±0.87) and heterozygosity values (H = 0.677±0.041, H = 0.857±0.016). Within population inbreeding estimate (F =0.215±0.040) showed moderate level of inbreeding, which warrant adoption of appropriate breeding strategies under field conditions. The polymorphism information content (PIC) value ranged from 0.531 to 0.915 suggested higher polymorphism in this breed. In general, the sign, standardized difference and Wilcoxon rank tests indicated heterozygosity excess in Kanni Adu goat population in infinite alleles and two-phase model and non-significant in stepwise mutation model. Hence, the mode-shift indicator test was utilized and it indicated the absence of genetic bottleneck in the recent past in Kanni Adu goats. It suggests that any unique alleles present in this breed may not have been lost. The study indicated that Kanni Adu goats exhibited substantial amount of genetic variation as reflected from the heterozygosity and number of alleles per locus.OtherItem Open Access Microsatellite-Based Genetic Profile and Phylogenetic Relationship Among Sheep (Ovis Aries) Breeds of Tamil Nadu(TANUVAS, Chennai, 2011-12) Karthickeyan, S.M.K.; Kathiravan, P.; Hepsibha, P.; Guru, V.; Sivaselvam, S.N.; Rahumathulla, P.S.ArticleItem Open Access Motility Characteristics of Bull Sperm by Computer Assisted Semen Analysis (CASA) and their Relationship with Hamster Egg Penetration Bioassay(TANUVAS, 2003) Kathiravan, P.; TANUVAS; Kalatharan, J.; Edwin, M.
