Figure 1:
Representative VLV chicken breed. (A and B) adult VLV rooster and hen at the time of sample collection (38 weeks of age); (C) VLV in a confined ground area at the growing stage, and (D) caged hens at the laying stage.
Figure 2:
Representative electrophoresis of the PCR products of 24 bp indel in the promoter region of the prolactin gene on 2% agarose gel. M: DNA ladder (50 bp). No. 1-4; 7-8 and 11: individual samples with DD genotype; Nos. 5-6 and 10: ID genotype; No. 9: II genotype; (-): Negative control.
Figure 4:
Genotype effects of the 24 bp indel prolactin gene on the accumulated number of eggs laid by VLV hens up to 38 weeks of age. ANE: accumulated number of eggs.
Figure 3:
Representative two sequences of the 24 bp PRL/indel in the promoter region. A: insertion of 24 bp (I allele) and B: deletion of 24 bp (D allele) at site 1819 (AF288765.2).
