1. Mantel test in population genetics
The comparison of genetic divergence or genetic distances, estimated by pairwise F ST and related statistics, with geographical distances by Mantel test is one of the most popular approaches to evaluate spatial processes driving population structure. There have been, however, recent criticisms and discussions on the statistical performance of the Mantel test

2. Desempenho de 79 progênies de soja na geração F6 e correlações fenotípicas, genotípicas e ambientais / Performance of 79 soybean progeny of F6 generation and their phenotypic, genotypic and environmental correlations
Soybean farmers have interest on increasingly early highly productive cultivars has stimulated the development of new genotypes for breeding soy programs. So that, this study aimed to evaluate the agronomic characteristics of 79 progenies of ten biparental crosses Program Soybean Breeding in Federal University of Uberlândia. The experiment was conducted at

3. Diversidade genética da abelha Eufriesea violacea (Hymenoptera, Apidae, Euglossini)
In this study six populations of Eufriesea violacea had their genetic structure and diversity estimated using microsatellite markers and mitochondrial obtained by PCR-RFLP. The samplings of male bees were carried out in Atlantic Forest remnants located in the states of Paraná (PR1, PR2, and PR3), São Paulo (SP1), Santa Catarina (SC1) and Rio Grande do Sul

4. A.N. Kolmogorov's defence of Mendelism
In 1939 N.I. Ermolaeva published the results of an experiment which repeated parts of Mendel's classical experiments. On the basis of her experiment she concluded that Mendel's principle that self-pollination of hybrid plants gave rise to segregation proportions 3:1 was false. The great probability theorist A.N. Kolmogorov reviewed Ermolaeva's data using a t

5. Risk perception for cancer and preventive behaviors in a sample of clients attending an outpatient cancer genetic counseling clinic / Percepção de risco para câncer e comportamentos preventivos em uma amostra de usuários de um ambulatório de aconselhamento genético oncológico
This study researched the perception of risk for developing cancer and preventive behaviors of individuals with suspect of hereditary cancer syndromes. It aimed to describe the perception of risk and causes of the main neoplasms related to hereditary cancer syndromes in a sample of users of a genetic counseling service for cancer; to associate behaviors adop

6. Seleção e análise dos modelos PARAFAC e Tucker e gráfico triplot com aplicação em interação tripla / Selection and analysis of the PARAFAC and Tucker models and triplot graphic with application in triple interaction
The present work has the following objectives: to propose a systematics for the study and the interpretation of the phenotypic stability and adaptability, through several multiway models (PARAFAC and Tucker3); to propose a graphic, called of Triplot, that it makes possible to evaluate the relations between the 3 ways (genotypes, locations and years); to impl

7. Apreciação de homens e mulheres maiores de 50 anos sobre a estética do envelhecimento
The ageing process is not only about genetics, it is also related to a life-style. It is a victory built throughout life. The genetics may postpone life, however, it does not guarantee quality of life. The goals of this study were to verify the reactions and attitudes of subjects aged over 50 years old related to body changes during the aging process. Prior

8. The Terminology of the Molecular Genetics: morphologic and semantic aspects" / A terminologia da Genética Molecular: aspectos morfológicos e semânticos
Taking into consideration that the units of specialized knowledge take part of a dynamic universe, in the scenery of the scientific innovations, and that they are basic for the specialized communication, the present work, in the fields of communicative/linguistic, has as main objective the systematization, organization and structuration of the vocabulary of

9. Attention déficit disorder (ADHD): socialdemographic description and study of candidates genes / "Transtorno de déficit de atenção e hiperatividade no adulto (TDAH): perfil sócio-demográfico e estudo de genes candidatos"
Background: Attention deficit hyperactivity disorder (ADHD) is an early onset neuropsychiatric disorder that affects 2% to 6% of school-age children and into adulthood in as 2/3 of the cases. Symptoms include impulsivity, inattention and hyperactivity. Its pathophysiology is thought to involve the dopaminergic pathway. These symptoms appears in childhood, bu

10. Biodisponibilidade como parÃmetro de qualidade e sua importÃncia no registro de medicamentos / Biodisponibility as a quality pattern and its importance to the registration of medicines.
This work will discuss the bioavailability of drug, how it is changed and its importance as a quality pattern to the registration of medicines in Brazil. In this light, bioavailability will be previously conceptualized and discussed together with other topics relevant to the comprehension of this work. Bioavailability can be affected by both the patient cond

11. Abordagem Bayesiana na análise genética de populações utilizando dados de marcadores moleculares. / Bayesian approach to the genetic analysis of populations using molecular markers data.
Among the various aspects generally considered in the genetic characterization of natural populations of plant species, the evaluation of the degree of genetic structure within and among individuals and the estimation of parameters related to the species mating system are of great importance. In general, considerable effort is focused on the estimation of th

12. Genotypic Correlation and Regression in Social Groups: Multiple Alleles, Multiple Loci and Subdivided Populations
Genotypic correlations and regressions can be estimated from multiallelic data sets either by weighting the allelic effects additively or by specifically weighting the genotypic interactions. Both methods can be extended to multiple loci, but they do not fully take into account the joint segregation patterns at the loci. These genotypic statistics have a gre
