[escepticos] poblaciones y grupos sanguineos

Hola, hola.

No es que tenga ni idea del tema, pero desde luego hay abundante 
literatura al respecto, para muestra dos botones:

Moors and Christians: an example of multivariate analysis applied to 
human blood-groups.

Reyment RA.

Published data on the frequencies of the alleles of the ABO, MNS, and 
Rh systems for populations in the western Mediterranean region are 
analysed by the multivariate statistical methods of canonical 
variates, principal components, principal coordinates, correspondence 
analysis and discriminant functions. It is shown that there is a 
'Moorish substrate' in the eastern and north-eastern parts of Spain 
and in southern Portugal. Serological effects, such as could derive 
from the assimilation of a large Jewish population, cannot be 
identified in the data available. The theory that most Hispano-Moslems 
and Spanish Jews were of indigenous origin is not gainsaid by the 
serological data available.

Genetics of the Chuetas (Majorcan Jews): a comparative study.

Picornell A, Castro JA, Misericordia Ramon M.

Universitat de les Illes Balears, Palma de Mallorca, Spain.

A study of the Chueta population has been carried out to establish the 
genetic relationships between the Chuetas and other Jewish and 
non-Jewish circum-Mediterranean populations and to identify which 
markers discriminate better between these populations. The analyses 
used were principal components analysis, factorial analysis of 
correspondences, and stepwise discriminant analysis. The results 
indicate that most of the Jewish communities resemble each other and 
other Middle Eastern populations, because of their common origin, but 
they also have affinities with their host peoples. The results also 
agree with those of most researchers in the importance of G6PD, FY, 
and MN as geographic markers and in the role of HP, GLO1, and Rh as 
indicators the Middle Eastern origin of the Jews but differ with 
respect to the geographic pattern of ABO. Moreover, the Jewish origin 
of the Chuetas remains evident in their genetic pool, although they 
resemble their neighboring populations more than other Jewish 
populations. Finally, HP, G6PD, ABO and Rh are the most important 
variables in determining the position of the Chuetas with respect to 
other Jewish and non-Jewish populations.


Es logico que las comunidades judias sean objeto de estudio, son 
poblaciones bastante aisladas y cuyos movimientos migratorios estan 
bien documentados.

PD: Se aproxima una nueva discusion sobre si existen o no las razas? 
Espero que no, aunque peor seria volver al tema de windows vs. linux 
:-)
