对6个白色来航鸡杂交群体的微卫星多态性及其与生长、产蛋量和免疫活性性状的关系进行了研究。九个微卫星标记进行了探讨，协会的研究使用最小二乘最大似然法对170只鸟的6个遗传群体。7个微卫星位点表现出多态性，有2 ~ 4个等位基因。5个标记的多态信息含量（PIC）均大于52%。微卫星MCW 0041、ADL 0210和MCW 0110与产蛋性状显著相关（P < 0.05）。MCW 0041基因型33的产蛋量最高，可达64周龄和72周龄。该标记的基因型11和13产生最低数量的卵。ADL 0210的杂合基因型34具有最高的产蛋量，直至52、64和72周龄。MCW 0110的纯合子11产生的卵子数量最多，可达28周龄。MCW 0041与28周龄和40周龄的体重显著相关（P < 0.05）。没有微卫星显着相关的蛋重在任何年龄，性成熟的年龄，或免疫反应绵羊红细胞。
Variability of microsatellites and a possible relationship with growth, egg production, and immunocompetence traits were estimated for six crossbred chicken populations of White Leghorn. Nine microsatellite markers were explored; an association study used the least square maximum-likelihood method on 170 birds of six genetic groups. Seven microsatellites were polymorphic, with two to four alleles. The polymorphism information content (PIC) of five markers was more than 52%. Microsatellites MCW0041, ADL0210, and MCW0110 were significantly (P < 0.05) associated with egg production traits. Genotype 33 of MCW0041 had the highest egg production, up to 64 and 72 weeks of age. Genotypes 11 and 13 of this marker produced the lowest number of eggs. The heterozygous genotype 34 of ADL0210 had the highest egg production, up to 52, 64, and 72 weeks of age. Homozygote 11 of MCW0110 produced the highest number of eggs, up to 28 weeks of age. MCW0041 was significantly (P < 0.05) associated with body weight at 28 and 40 weeks of age. No microsatellite was significantly associated with egg weight at any age, with age at sexual maturity, or with immune response to sheep RBC.
