摘要：
遗传学的技术进步已经引起了分子系谱学的科学，通过给我们机会从一个新的角度来研究谱系，同时检查活着的人，而不是整理他们祖先的记录。一个四代母系家谱是由大安吉拉Antunez（b。a. 1881年在西班牙巴塞罗那）给他们在古巴和哥斯达黎加的后代。所观察到的线粒体谱系在HVR 1区域相对于参考序列（CRS）有一个取代，属于H单倍群。这是一致的-正如预期的那样，与最近记录的欧洲血统。这是妇女移徙差异的一个例子，妇女移徙到丈夫的原籍地。由于在大多数社会中实行父系婚姻，这种迁移机制产生了重大影响，因为移民妇女的到来带来了新的和不同的mtDNA谱系，这与混合过程一起有助于丰富美洲人口基因库的多样性和区域化。
英文摘要：
The technological advances in Genetics have given rise to the science of Molecular Genealogy, by giving us the opportunity to approach the study of pedigrees from a new perspective, examining alive people at the same time than collating records from their ancestors. A four generations matrilineal genealogy is presented from Da. Angela Antunez (b. a. 1881 in Barcelona, Spain) to their descendants in Cuba and Costa Rica. The observed mitochondrial lineage has a substitution in the region HVR1 respect to the reference sequence (CRS) and belongs to H haplogroup. This is consistent -as expected, with the recent documented European lineage. This is an example of differential female migration, in which women move to the husband's place of origin. Because of patrilocal marriages are practiced in most societies, such migration mechanism has had a major impact since the arrival of immigrant women bring new and different lineages of mtDNA, which together with the admixture process contributed to enrich the diversity and regionalization of the gene pool of human populations in the Americas.
