WL-G (White Leghorn breed)

Origin

Established at Faculty of Agriculture, Nagoya Univ. (1969)

Characteristics

This line is the oldest closed colony that is established in Nagoya Univ. (over 40 years). Its MHC haplotype is fixed to B12 and skin graft within a line is acceptable. 2', 5'-oligoadenylic acid synthetase was fixed to A/A type. The repeat number in region of dopamine receptor (D4exon I) was fixed to a long type (9/9). The result of survey for 40 microsatellite markers was that 18 loci were segregated and 22 were fixed.

Origin

Introduced from Okazaki farm, National Livestock Breeding Center (around 1980)

Characteristics

This line is a dual purpose breed for egg and meet. Its MHC haplotype seems to be fixed to B12 but some chickens were rejected for skin graft within a line. The result of survey for 40 microsatellite markers was that 30 loci were segregated and 10 were fixed.
