鸡12周龄体重的主基因+多基因混合遗传分析
Analysis of Mixed Major-gene with Polygenes Genetic Model for Chicken Body Weight at 12 Weeks Age
摘要
Abstract
The inheritance for 12 weeks' weight in chicken may provide the foundation for its mechanisms, coarse and fine mapping of quantitative trait loci (QTL), breeding and marker assisted selection to body weight. Therefore, joint segregation analysis of P1, F1 , P2 and F2 populations derived from a cross between Xianju chicken and Recessive White chicken was used to study the inheritance in this study. The individuals of the four populations mentioned above were measured for the trait. The observations between cock and hen and between the direct and reciprocal crosses were corrected. The results showed that 12 weeks'weight in chicken was controlled by two codominance major - genes with additive - dominan polygene, and the heritability was 0.610 4 for major-gene and 0. 165 9 for polygenes.关键词
