Genotypic and allelic frequency at the SNP locus of ADRA1B and PPARGC1B genes in the Dagu chicken population

SNP	Genotype	No. of chickens	Genotype frequency	Allele	Allele frequency	x2
A1915G (ADRA1B)	AA	260	0.722	A	0.861	12.69 *
	AG	100	0.278	G	0.139
T6146C (PPARGC1B)	TT	268	0.744	T	0.872	7.70*
	TC	92	0.256	C	0.128

SNP, single nucleotide polymorphism; ADRA1B: adrenergic, alpha-1B-, receptor; PPARGC1B: peroxisome proliferator-activated receptor gamma, coactivator 1 beta.

^*p<0.05 was accepted to be statistically significant when the data were analyzed using a Pearson’s goodness-of-fit chi-square test (degree of freedom=1).
