摘要:The prospective study was undertaken in the service of Maternity and Gynaecology (Hospital Cherif Idrissi to Kénitra) to determine the biodemographic and genetic structure of the population of the Gharb in Morocco through the study of the surname characteristics (whose transmission is similar to that of the Y chromosome) and the analysis of the consanguinity.
The results reveal a high rate of endogamy according to the birthplace of spouses. The mean coefficient of consanguinity, based on surnames frequency is twice superior than that estimated by genealogies (generation of the studied couples and generation of their parents) with a more heterogeneous distribution.
Thus, the usefulness of surnames for inferring about population structure is supported, as well as the usefulness of historical information for explaining genetic diversity.
