Through genetic analysis, they identified a chromosomal region associated with feather-pecking damage.
Of these intervals, significant attention has been directed at the 1q41-42 chromosomal region.
A t-haplotype is a designation for a chromosomal region adjacent to or encompassing the H2 complex.
Six human chromosomal regions were found that may have been under particularly strong and coordinated selection during the past 250,000 years.
Therefore, the pooled analysis did not formally confirm any previously identified chromosomal regions of interest (see below).
Four cases (27%) were, however, consistent with genetic heterogeneity at this chromosomal region.
The fragment, known as the "bait", contains the site that associates with other chromosomal regions.
No genes have been identified yet but genetic linkage has been established with several chromosomal regions.
Nor was there any association between the chromosomal region and female sexual orientation.
