Abstract
Formulae are suggested to analyse the variance of chromatids in karyotypes with replicated chromosomes. For chromosomes 1, 2 and 3, it is possible to analyse the variance between sister chromatids, the variance between replicated chromosomes and the variance between homologous chromosomes. It is also possible to compare the total variance of chromatids (1, 2 or 3) with the variance originating only in errors of measure.
Résumé
Une analyse de la variance est proposée pour comparer la variance entre chromatides soeurs, celle entre chromosomes d'un même doublet et celle entre doublets homologues, un doublet se composant d'um chromosome et de sa copie obtenue par endoréduplication. La variance totale des chromatides est comparée à celle due uniquement aux erreurs de mesure.
