Identification of polymorphisms associated with production traits on chicken (Gallus gallus) chromosome 4

F. Pértille, Zanella, R., Felício, A. M., Ledur, M. C., Peixoto, J. O., and Coutinho, L. L., Identification of polymorphisms associated with production traits on chicken (Gallus gallus) chromosome 4, vol. 14, pp. 10717-10728, 2015.

Genetic selection for production traits has resulted in a rapid improvement in animal performance and development. Previous studies have mapped quantitative trait loci for body weight at 35 and 41 days, and drum and thigh yield, onto chicken chromosome 4. We investigated this region for single nucleotide polymorphisms and their associations with important economic traits. Three positional candidate genes were studied: KLF3 (Krüeppel-like factor 3), SLIT2 (Slit homolog 2), and PPARGC1A (peroxisome proliferator-activated receptor gamma, coactivator 1 alpha).
