Heritability of 20 anthropometric traits was assessed by multiple regression analyses on 305 Mexican families. For most of the studied traits a high coefficient of heritability (range between 0.6 and 0.9) and a high and significant additive component of genetic variance were found. Only in three traits did the non-additive component have a significant value. By principal component analy sis all the studied traits were separated into eight independent groups. Segregations of these traits in offspring from the modal morphological types of parents were in agreement with the expected distributions and consequently supported the concept of a Mendelian heritability of these traits. Zusammenfassung: Bei 305 mexikanischen Familien wurde die Erblichkeit von 20 anthropometri schen Merkmalen mit Hilfe einer multiplen Regressionsanalyse abgeschatzt. Bei den meisten unter suchten Merkmalen wurden ein hoher Heritabilitatskoeffizient (Bereich zwischen 0,6 und 0,9) und eine hohe und signifikante additive Komponente genetischer Varianz gefunden. Nur bei drei Merk malen hatte die nicht-additive Komponente einen signifikanten Wert. Mit Hilfe der Hauptkompo nentenanlyse wurden alle untersuchten Merkmale in 8 voneinander unabhangige Gruppen getrennt. Die Trennung dieser Merkmale nach Abkommlingen von den morphologischen Eltern-Typen fiihrte zu den erwarteten Verteilungen und stiitzt somit das Konzept des Mendelschen Erbgangs fur diese Merkmale.
