Marker-trait association analysis
The results of the general linear model (GLM) analysis of
the association between the myostatin gene
polymorphisms and growth traits for the female Bian
chickens are presented in Table 3. The body weight of the
Bian chickens of the QQ genotypes were the lowest from
hatching to 18 weeks. Bian chickens of the QR genotype
had higher body weight than those of the QQ genotype
(P < 0.05 or P < 0.01) from 8 to 12 weeks of age.
Chickens of the RR and QR genotypes had higher body
weight than those of QQ genotype from 14 to 18 weeks
of age. The differences for growth traits between the QR
and RR genotypes were not significant (P > 0.05) from
hatch to 18 weeks.
