    Notes: Abstract A migration with admixture of genes in two populations inducesHL-A linkage disequilibrium or Δ when gene frequencies in the two populations are dissimilar. Since theHL-A linkage disequilibrium disappears very slowly, this factor could be used to recognize some migrations. In the recent migration of American Negroes, a dilution of Caucasoid disequilibrium is noted. By the presence of Δ values, a study of possible migrations around the world is reported and a brief comparison with other methods of research into population origins is discussed in connection with the European ecosphere: a well-known expansion axis is found from East to West (probably due to the Indo-European migration), which ends with admixture with various local Western European populations. Another expansion of genes is noted from the North of Europe towards the Southwest.

    Notes: [Auszug] The spermatozoa were collected from nine healthy donors (40 to 60 years old) obtained from a panel of donors previously typed for HL-A antigens by the lymphocytotoxicity test2. The semen was washed immediately after collection in phosphate buffered saline (pH 7.2), containing 0.2 per cent bovine ...

    Description / Table of Contents: Résumé Observation d'une modification de l'expression du gène A chez un enfant, trisomique p18 et trisomique p20, issu d'une famille dont deux générations présentent une translocation 18, 20, héritée du grand-père et transmise avec le même haplotype HL-A.
    Abstract: Zusammenfassung Es wird die Beobachtung einer Modifikation der Expression des Gens A bei einem Kinde mitgeteilt mit partieller Trisomie p18 und p20. Es gehört einer Familie an, in der durch zwei Generationen eine vom Großvater überkommene Translokation 18, 20 mit dem gleichen HL-A-Haplotyp vererbt worden ist.
    Notes: Summary The case of a modified expression of the A gene in a child with partial trisomy p18 and p20 is described. An 18, 20 translocation passed on by the child's grandfather has been inherited with the same HL-A haplotype in two generations of the family.
