OMIA 001942-9913 : Haplotype with homozygous deficiency JH2 in Bos taurus

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive Lethal

Considered a defect: yes

Key variant known: no

Species-specific name: Haplotype JH2

Species-specific symbol: JH2

Mapping: Using a strategy similar to that of VanRaden et al. (2011), VanRaden et al. (2014) discovered reduced-fertility haplotype JH2, located on chromosome BTA26 at 8.8-9.4Mb.

In their table of reduced-fertility haplotypes, Cole et al. (2014) list this haplotype as being located at 8,812,759 – 9,414,082bp on chromosome BTA26.

Breed: Jersey.
