Quantitative genetics of cranial nonmetric traits in randombred mice: heritability and etiology.
Cheverud and Buikstra (1981) demonstrated a tendency for nonmetric traits representing the number of foramina to have lower heritabilities than those representing hyperstotic or hypostotic traits in a sample of rhesus macaques. Based on this observation, Cheverud and Buikstra hypothesize that differences in the heritability of the two sets of traits may be due to differences in trait etiology. ...
متن کاملThe Relationship Between Cranial Metric and Nonmetric Traits in the Rhesus Macaques From Cay0 Santiago
This study addresses the relationship between cranial metric variables and nonmetric traits using the skeletal sample of rhesus macaques from Cay0 Santiago. Discriminant function analysis is used to study the metric differences between macaque crania grouped according to the presence or absence of nine nonmetric traits. The computation of total structure coefficients from the discriminant funct...
متن کاملData Error Reduction in Nonmetric Multidimensional Scaling
The aim of Multidimensional Scaling (MDS) is to search for a geometrical pattern of n points, on the basis of experimental dissimilarities data between these points. For nonmetric MDS, one may use ordinal data as dissimilarities. In general, as these dissimilarities are empirical, they may be errorful. Thus, in order to obtain better scaling solutions, it is of great interest to reduce error in...
متن کاملAdvanced CT images reveal nonmetric cranial variations in living humans
Two mainland Japanese males were examined with a computer tomography (CT) X-ray scanner to reconstruct three-dimensional CT simulation images of their cranial anatomy and to check for the presence/absence of 23 nonmetric cranial traits. Surface anatomy for scoring 19 nonmetric cranial variations was clearly observed among the 23 variations. Evaluation of the four other traits might have been di...
متن کاملBrief communication: cranial nonmetric trait database on the internet.
This brief note announces the publication of a nonmetric cranial trait database as a freely available resource on the Internet at: http://library.queensu.ca/webdoc/ssdc/cntd. The files were constructed in the program Excel, and are available also in comma-delimited format. These one-observer data on 38 traits were recorded in 1963-2003 in skeletal collections curated at many museums. The 8,016 ...
