OBR基因及其作为鹅脂肪性状遗传标记的用途
摘要：
一种OBR基因及其作为鹅脂肪性状遗传标记的用途，测定出OBR基因中与腹脂重、腹脂率和血浆VLDL浓度相关的遗传标记，并测定从该动物获得的核酸样品中OBR(obese receptor)基因中多态性的存在，该多态性是与腹脂重、腹脂率和血浆VLDL浓度相关的多态性，并可根据该基因的单核苷酸多态性可对基因组DNA中含有OBR基因的动物进行脂肪性状选育，筛选出降低鹅腹脂重、腹脂率和血浆VLDL浓度的优势基因型，具有极其重大的应用价值和经济效益。
摘要（英）：

The invention relates to an OBR (obese receptor) gene and application thereof as goose fat traits genetic markers. Genetic markers related to abdomen fat weight, abdomen fat ratio and blood plasma VLDL (Very Low Density Lipoprotein) concentration in the OBR gene are measured; the existence of polymorphism in the OBR gene in a nucleic acid sample obtained from a goose is measured, wherein the polymorphism is related to the abdomen fat weight, the abdomen fat ratio and the blood plasma VLDL concentration; and the fat traits selection breeding can be carried out on the goose containing the OBR gene in a genome DNA according to the single nucleotide polymorphism of the gene, and an advantageous genotype for reducing the abdomen fat weight, the abdomen fat ratio and the blood plasma VLDL concentration is obtained by the screening. Therefore, the invention has extremely important application value and economic benefit.
