Quantitative Genetics Model as the Unifying Model for Defining Genomic Relationship and Inbreeding Coefficient
The traditional quantitative genetics model was used as the unifying approach to derive six existing and new definitions of genomic additive and dominance relationships. The theoretical differences of these definitions were in the assumptions of equal SNP effects (equivalent to across-SNP standardization), equal SNP variances (equivalent to within-SNP standardization), and expected or sample SN...
متن کاملRelationship between Coefficient of Inbreeding and Parasite Burden in Endangered Gazelles
We studied the effects of inbreeding depression on parasite infection in three species of endangered gazelles: Gazella cuvieri , G. dama, and G. dorcas . Coefficients of inbreeding were calculated for all individuals because complete genealogies were available. The levels of inbreeding differ both intraand interspecifically. We collected samples of feces and determined nematode infection by cou...
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 coefficient and heterozygosity-fitness correlations in unhatched and hatched song sparrow nestmates.
Heterozygosity-fitness correlations use molecular measures of heterozygosity as proxy estimates of individual inbreeding coefficients (f) to examine relationships between inbreeding and fitness traits. Heterozygosity-fitness correlations partly depend on the assumption that individual heterozygosity and f are strongly and negatively correlated. Although theory predicts that this relationship wi...
متن کاملBiology: Breeding IMPLICATIONS OF INBREEDING COEFFICIENT AND COANCESTRY IN A SUGARCANE BREEDING PROGRAM
Inbreeding coefficients and coancestry were used to investigate the genetic base in the Taiwan sugarcane breeding program. Six of the potentially most important ROC varieties in Taiwan were studied. Four ROC varieties had inbreeding coefficients. The largest inbreeding coefficient was found in ROClO (0.281), followed by ROC9 (0.156). Since ROC9 and ROClO are currently the leading cane varieties...
متن کاملPedigrees or markers: Which are better in estimating relatedness and inbreeding coefficient?
Individual inbreeding coefficient (F) and pairwise relatedness (r) are fundamental parameters in population genetics and have important applications in diverse fields such as human medicine, forensics, plant and animal breeding, conservation and evolutionary biology. Traditionally, both parameters are calculated from pedigrees, but are now increasingly estimated from genetic marker data. Concep...
