Abstract Allometry has been the focus of growing interest in studies using geometric morphometric methods to address a wide range research questions at interface ecology and evolution. This study uses computer simulations compare four for estimating allometric vectors from landmark data: multivariate regression shape on measure size, first principal component (PC1) shape, PC1 conformation space...

Data from 1006 pigs selected for breeding and subsequently scored at 22-24 weeks of age were used to estimate heritabilities for conformation traits. Front wrists, front pasterns, back hocks, back pasterns, front view, rear view and back shape were each subjectively scored by a single operator. For the individual traits heritability estimates ranged from high (0.42±0.09 for front pasterns) to n...

IOLOGISTS have long directed attention to problems relating to the B determination of quantitative measures of body conformation and the genetic factors responsible for variation in conformation. Such variation in conformation hetween individual aninials within a species is due to differences in the relative proportions of the various parts to each other and to the animal as a whole. D’ARCY p t...

B ODY conformation in cattle is one of the important bases in judging and selecting animals for breeding and production purposes. Measurements taken on various parts of the body furnish an objective description of body conformation. The ability of cattle to produce meat could be estimated with these measurements if relationships between body measurements and meat production characters were obta...

FT-IR and FT-Raman spectra of hirudin have been recorded from the native solid hirudin. The conformation of the molecule has been discussed on the basis of IR and Raman data. It has been concluded that hirudin molecule has a mixed a-helix and random coil conformation.
