Age estimates based on Y-chromosome microsatellite diversity place the initial settlement of the American continent at approximately 14,000 years ago, in relative agreement with the age of well-established archaeological evidence. Expand

It is estimated that this colonization involved about 100 individuals and occurred some 13,000 years ago, in agreement with well-established archeological data, and that a single, discrete, wave of colonization is highly inconsistent with observed levels of genetic diversity. Expand

Analysis of mtDNA restriction fragment polymorphisms in Amerinds from North, Central and South America agree with previous findings in not supporting a higher migration rate for women in these populations and suggest the existence of a North to South gradient of increasing drift in the Americas.

[Genetic linkage analysis of Gilles de la Tourette Syndrome in a Colombian family].
The linkage values for D20S1085 and D6S477 markers are suggestive and therefore it is not possible reject that these markers will be in linkage disequilibrium with genes involved in the GTS, ADHD, OCD, MT, and PT etiology. Expand
