Method of judging economic genetic traits by Calcium Sensing Receptor in chicken

摘要

The present invention relates to a method for determining the genetic economic trait of a chicken by using a calcium sensor receptor gene of chicken, (a) for amplification corresponding to the genomic gene of the chicken sample and the calcium sensor receptor (CaSR) gene derived from chicken Amplifying the calcium sensor receptor gene by PCR using a primer; (b) SNPs of the amplified calcium-sensing receptor genes to the restriction enzyme Nco I by RFLP method, and then the SNP for each sample according to the difference in allelic type due to the missense mutation (base substitution) of the calcium-sensing receptor in the gene processing product Detecting a labeling factor; And (c) predicting the gestational age, egg weight, spawning number or body weight of the chicken from the detected SNP labeling factor.;It is believed that the present invention can play a very important role in improving the economic quality of chickens.;Chicken, calcium receptor, SNP, improved
