【 摘 要 】

We used nine morphological genes to analyze cat populations from Mexico, the Dominican Republic, the Colombian, Brazilian and Peruvian Amazon, Bolivia and Brazil. Most populations were in Hardy-Weinberg equilibrium at the O locus. The highest allele frequencies so far detected at world level for alleles I (inhibitor) and L (long hair) were found at La Paz (Bolivia). The analyses revealed at least five cat gene pools in Latin America: These findings suggest that the current genetic distribution of cats in Latin America correlates with the colonization of the Americas during the XIV to XVIII centuries. Additionally, the cat populations of São Paulo, Rio de Janeiro and Manaus were sampled, to compare their 1996-2003 genetic profiles with those obtained in 1983. Generally, these genetic profiles seem temporally stable, which is important for comparing cat populations sampled in different years and decades.
