Abstract

The insulin-like growth factor, IGF-I, plays an important role in the development of growth and reproductive traits. Single-strand conformation polymorphism analysis was used to detect and analyze polymorphisms and expression profiles of the IGF-I gene and its association with growth and reproductive traits of Jinghai yellow chickens. A point mutation g.295T>C was detected in the IGF-I gene with three genotypes CC, CT, and TT. The CT and TT genotypes were found to be significantly (P C mutation in the IGF-I gene affects certain growth and reproductive traits, and it could be used to provide a theoretical basis as well as marker-assisted selection to upgrade the development of Jinghai yellow chickens in future.
