1. Assessing paternity in japanese quails (Coturnix japonica) using microsatellite markers - inferences for its mating system and reproductive success
Microsatellite markers were analyzed in Japanese quails, Coturnix japonica, using different methodologies (PAGE and automated genotyping), in order to evaluate their use in paternity testing. Ten animal triplets composed by a female and two males were used to mate and generate an offspring. Paternity was determined in five-day-old embryos, and the data gener

2. Analysis of seven STR human loci for paternity testing by microchip electrophoresis
The aim of this work was to evaluate two paternity cases by microchip electrophoresis and the validation of the methodology by comparison of the results with those obtained in a commercial genetic analyzer. It was observed that when working with tetranucleotide regions, in which the minimal difference between the alleles was only four base pairs, the commerc

3. Os sentidos da paternidade : dos "pais desconhecidos" ao exame de DNA / The meanings of paternity : from "unknown fathers" to DNA testing
The present thesis analyses the life narratives of children that have searched at the present for the legal recognition of the biological father in order for us to understand how the meanings of fatherhood are constituted, are signified and re-signified in these particular experiences, questioning at the same time how paternity, filiation, and conjugality ar

4. Allelic frequencies and statistical data obtained from 12 codis STR loci in an admixed population of the Brazilian Amazon
The allelic frequencies of 12 short tandem repeat loci were obtained from a sample of 307 unrelated individuals living in Macapá, a city in the northern Amazon region, Brazil. These loci are the most commonly used in forensics and paternity testing. Based on the allele frequency obtained for the population of Macapá, we estimated an interethnic admixture f

5. Estudos de locos de características quantitativas, de expressão gênica e teste de paternidade em suínos / Studies of quantitative trait loci, genic expression and of paternity testing in pigs
The accomplishment of the present study had as objective: 1) to map Quantitative Trait Loci (QTL) on chromosomes 1, 2, 3, 12, 14, 15 and X in a F2 pig population developed by mating two Brazilian Piau breed sires with 18 dams from a commercial line (Landrace × Large White × Pietrain); 2) investigate the level of expression of candidate genes influencing ec

6. Estudo genético de populações caprinas locais e exóticas através de marcadores microssatélites
The aim of the present study was develop a panel of microsatellites for testing paternity in goats as an aid for conservation and improvement programs for local breeds. A total of 381 animals from 10 goat populations [six local Brazilian ecotypes/breeds (Azul, Canindé, Graúna, Marota, Moxotó and Repartida) and four exotic breeds currently used in Brazil (

7. Genetic variability and efficiency of DNA microsatellite markers for paternity testing in horse breeds from the Brazilian Marajó archipelago
In this study, 15 microsatellite DNA loci used in comparative tests by the International Society for Animal Genetics were applied to the evaluation of genetic diversity and management, and the efficiency of paternity testing in Marajoara horses and Puruca ponies from the Marajó Archipelago. Based on the genotyping of 93 animals, mean allelic diversity was e

8. DNA testing for parentage verification in a conservation nucleus of Pantaneiro horse
We investigated the genealogy of the in situ conservation nucleus of the Pantaneiro horse using DNA microsatellites by evaluating 101 horses, the group consisting of 71 adult horses (3 stallions, 40 male and 31 mares) and 27 foals (14 colts and 13 fillies). Genomic DNA was extracted from hair roots and genotyped using 12 microsatellite markers (AHT4, AHT5, A

A definiÃÃo das taxas de mutaÃÃo dos locos de microssatÃlites ou Short Tandem Repeats (STRs) usados em anÃlises forenses sÃo Ãteis para a correta interpretaÃÃo dos resultados dos perfis genÃticos e para a definiÃÃo dos critÃrios de exclusÃo em testes de paternidade. MutaÃÃes da linhagem germinativa de 14 locos de STRs foram estudadas atravÃ

10. Variabilidade e desempenho forense de microssatélites utilizados na verificação de parentesco do plantel brasileiro de cavalo puro sangue inglês (PSI)
Thoroughbred horses (TB) is a breed derived from a considerably narrow genetic base involving a few founder stallions, displaying today a reduced allelic diversity when compared to other horse breeds. TB animals, however, demand a very high rigor in the genealogical control in view of its international reputation and ample worldwide trading in which Brazil p

11. Study of allelic frequency of five X-Chromosome?s loci STR on Sao Paulo State people and its role in human identification / Estudo de freqüência alélica de cinco loci STR do cromossomo X na população do Estado de São Paulo e sua contribuição na identificação humana
The forensic identification through DNA analysis is, frequently, done by the study of DNA?s polymorphic regions, such as STR, short tandem repeats. In order to use these markers in human identification, it?s necessary to know the allelic distribution in the population in wich the person belongs. This research aimed to settle the allelic frequencies of five X

12. Paternity testing and behavioral ecology: a case study of jaguars (Panthera onca) in Emas National Park, Central Brazil
We used microsatellite loci to test the paternity of two male jaguars involved in an infanticide event recorded during a long-term monitoring program of this species. Seven microsatellite primers originally developed for domestic cats and previously selected for Panthera onca were used. In order to deal with uncertainty in the mother's genotypes for some of
