estimation of inbreeding coefficient and its effects on lamb survival in sheep
introduction the mating of related individuals produces an inbred offspring and leads to an increased homozygosity in the progeny, genetic variance decrease within families and increase between families. the ration of homozygosity for individuals was calculated by inbreeding coefficient. inbred individuals may carry two alleles at a locus that are replicated from one gene in the previous genera...
متن کاملHigh inbreeding in sheep or erroneous estimation?
Paiva et al. (2011) examined how microsatellite loci data from sheep surveys in the United States and Brazil could be merged when they are analyzed in different laboratories. In addition, they calculated the inbreeding coefficient using F IS from the software FSTAT (Goudet 2001) using the formula F H H IS O E 1 = − / , where H O and H E are the observed and expected Hardy–Weinberg heterozygosit...
متن کاملEstimation of the inbreeding coefficient through use of genomic data.
Many linkage studies are performed in inbred populations, either small isolated populations or large populations with a long tradition of marriages between relatives. In such populations, there exist very complex genealogies with unknown loops. Therefore, the true inbreeding coefficient of an individual is often unknown. Good estimators of the inbreeding coefficient (f) are important, since it ...
متن کاملInbreeding and Inbreeding Depression on Body Weight in Iranian Shal Sheep
The aim of this study was to estimate amount of inbreeding coefficient in Shal sheep and its impact on growth performance. Pedigree information and body weight at different ages (birth weight, 3 month weight, 6 month weight, 9 month weight and 12 month weight) were used from 6692 lambs from 90 rams and 1007 ewes. Data were collected on Ghazvin sheep breeding station during 1997-2013. Estimation...
متن کاملEstimation of Inbreeding Coefficients Using Pedigree and Microsatellite Markers and Its Effects on Economic Traits of Shirvan Kordi Sheep
In this study, pedigree data of 7170 lambs produced from 177 rams and 2182 ewes collected during 1989 to 2009 in the Shirvan Kordi sheep breeding station, were used for calculating inbreeding coefficients. The impact of inbreeding on the studied traits was investigated by including inbreeding coefficients for each animal as a covariate in the animal model. Average inbreeding coefficient of the ...
