13. Genotype by environment interaction in different birth seasons for weight at 240, 365 and 450 days of age in Tabapuã cattle
The objective of this study was to evaluate the effect of genotype by environment interaction (GEI) on the weight of Tabapuã cattle at 240 (W240), 365 (W365) and 450 (W450) days of age. In total, 35,732 records of 8,458 Tabapuã animals which were born in the state of Bahia, Brazil, from 1975 to 2001, from 167 sires and 3,707 dams, were used. Two birth seas

14. Genetic evaluation of European quails by random regression models
The objective of this study was to compare different random regression models, defined from different classes of heterogeneity of variance combined with different Legendre polynomial orders for the estimate of (co)variance of quails. The data came from 28,076 observations of 4,507 female meat quails of the LF1 lineage. Quail body weights were determined at b

15. Variable clinical expression in patients with a germline MEN1 disease gene mutation: clues to a genotype-phenotype correlation
Multiple endocrine neoplasia type 1 is an inherited endocrine tumor syndrome, predominantly characterized by tumors of the parathyroid glands, gastroenteropancreatic tumors, pituitary adenomas, adrenal adenomas, and neuroendocrine tumors of the thymus, lungs or stomach. Multiple endocrine neoplasia type 1 is caused by germline mutations of the multiple endoc

16. Análise da dispersão das populações nativas americanas: uma abordagem genético-fisiográfica / Dispersion analysis of the native american populations: a genetic-fisiographyc approach
Until recently, the settlement of the Americas was seen as the product of a \"bow wave\" human expansion from north do south. Under this scenario, the archaeological sites of the first americans should obey a chronological gradient following the same logic, independent of their longitude. Recently, however, specialists began to recognize that certain charact

17. Heterogeneity of linalool chemotypes of Lippia alba (Mill.) N.E.Br., based on clonal half-sib progenies
Lippia alba (Mill.) N.E.Br. is an aromatic and medicinal shrub native to the American continent. Despite its potential as a source of essential oil for the pharmaceutical and cosmetics industries, few selection and genetic improvement studies have been carried out. The aim of this study was to provide genetic information on this species for breeding programs

19. Components of variance and interaction between genotype and environment for annual girth increment in rubber tree.
To determine the nature and extent of genetical and environmental control of vigour through annual girth increment in rubber trees [Hevea brasiliensis (Willd.ex Adr. de Juss.) Muell.Arg.], seven clones were studied in a replicated trial in Sao Paulo State at four different locations. The clones represented a range of imported germplasm while the locations we

20. Genetic analyses of days to calving their relationships with other traits in a Canchim herd.
Heritabilities and genetic correlations in a Canchim beef cattle herd were estimated using data on the following traits: male scrotal circumference at twelve months (SC12); days to first calving (DFC) for heifers; days to calving (DC) for cows; male and female weight (W) at twelve months (W12); heifer weight at the start of the first breeding season (WFBS) a

21. Activity of beta-glucosidase and levels of isoflavone glucosides in soybean cultivars affected by the environment.
The enzyme B-glucosidade hydrolyses the isoflavone glucosides developing aglycones, which are compounds with anticancer effects, that are also related with the astringency observed in soybean flavor. Due to the importance of this enzyme, a study was carried out to determine B-glucosidade activity in soybean (Glycine max (L.) Merrill) cultivars with different

22. Estudos dos pigmentos visuais de macaco-prego (cebus sp) e da relação entre a psicofísica e a genética da visão de cores em humanos / Study of the visual pigments from capuchin monkey (Cebus sp) and the psychophysics and the genetics colour vision relationship in humans
Color vision is possible due to different types of photoreceptors and to the post receptoral processing of the information generated after cell activation by the light. Genetic, functional and morphological analysis can be used as tools in the color vision studies. In the present work the genetic of the visual pigments from Cebus sp and the genetic and the p

23. Uso da seleção genômica e fenotípica em linhagens para a predição de testecrosses em milho / Use of genomic and phenotypic selection in lines to predict maize testcrosses
Há tempos os melhoristas tentam prever as performances de híbridos a partir de informações das suas linhagens parentais. A aplicação mais promissora dos marcadores moleculares no melhoramento de plantas é sua utilização na seleção. A produção de grãos é o caráter de maior interesse para os melhoristas e caracteriza-se por ser controlado por g

24. Modelagem de nicho em espécies de plantas do Cerrado e distribuição espacial da variabilidade genética / Niche modeling of plants species from the Cerrado and spatial distribution of genetic variability
Ecological and evolutionary factors may explain the patterns of intrapopulation variability across the geographic distribution of a species. More suitable habitats, in ecological terms, allow the survival of greater number of individuals, which increases the genetic variability in the population, while in less suitable habitats, because of smaller population
