Morphological traits such as brachycephaly are characteristic of certain breeds and had a functional purpose at the time that those breeds were created.
From Central Asia eastward to the Pacific Islands and subcontinents on the one hand, and to America on the other, brachycephaly and orthognathism gradually diminish, and are replaced by dolichocephaly and prognathism, less, however, on the
Among the characteristics of the yellow or xanthodermic race are: deficient length of the limbs; total height 7 to 7.5 heads; mamma papillata; brownish-yellow to light yellow skin, coarse and black hair of the head, with a round cross - section; hair on the body scant; inclination to brachycephaly; broad, short jaw; slight frontal ridge; short, small, strong foot with moderate arch.
Thus the vast majority of heads are mesaticephalic with more tendency toward brachycephaly than to dolichocephaly.
On the other hand, high cheek-bones and broad faces -- a condition most usually found associated with brachycephaly -- have sometimes been noted as associated with undue or violent sexuality.
On the other hand, the Borreby skulls are all somewhat broader, in proportion to their length, than the Neanderthal skull, while some attain that proportion of breadth to length (80: 100) which constitutes brachycephaly.
In this study we identified the major locus for brachycephaly using an across breed genome-wide association mapping strategy with only a small number of dogs.
In order to further confirm the chromosome assignment for brachycephaly, a second independent data set was used for genome wide association.
The second candidate gene for brachycephaly, SMOC2, was located just outside of the critical interval for brachycephalic head type.
There is little variation within these breeds for brachycephaly, indicating that individuals are largely fixed for the causative allele.
