| 主要内容：An analysis of a selection experiment was used to assess the impact of various animal model structures on REML estimates of variance components.The analyses were carried out based on 162 d body mass(BM) of 1287 animals from 21 paternal half-sib groups of Fenneropenaeus chinensis.Estimated breeding values(EBV) of BM of all individuals were estimated using eight statistical models(A,AB,ABC,ABDC,ABMFC,ABMDC,ABFDCandABMFDC) and BLUP(best linear unbiased prediction),These models were designed involving factors such as sex,spawn date as fixed effects,maternal genetic efects,full-sib family efects as random efects,mean BM of families at tagging and age at recording(covariate).The results demonstrate the importance of correct interpretation of efects in the data set ,particularly those that can inlfuence resemblance between relatives.The data structure and the particular model that was applied markedly influenced the..... |
