Genetic avaluation for persistency of lactation in Holstein cows using a random regression model
(2007) [Artículo de periódico]A model for analyzing test day records including both fixed and random coefficients was applied to the genetic evaluation of first lactation data for Holstein cows. Data comprising 87045 test-day milk yield records from ... -
Genetic basis of reproductive performance and antibody response in pigs during a porcine reproductive and respiratory syndrome outbreak
(2020) [Tesis de maestría]Total antibody response, measured as sample-to-positive ratio (S/P ratio), has been proposed as an indicator trait to improve reproductive performance in pigs infected with the porcine reproductive and respiratory syndrome ... -
Genetic characterization of a brangus-ibage cattle population-biochemical polymorphisms and reproductive efficiency
(2000) [Artículo de periódico]Técnicas bioquímicas foram utilizadas para determinar a variabilidade genética numa população de bovinos da raça Brangus-Ibagé com relação a 18 sistemas protéicos sangüíneos: Hemoglobina - Cadeia b (Hb), Albumina (Alb), ... -
Genetic components affecting embryonic developmental time of Drosophila melanogaster
(2002) [Artículo de periódico]The developmental time of the embryonic stage of Drosophila melanogaster was 21.66% faster and 14.75% slower than controls in populations selected for fast and slow developmental speed, respectively. The genetic model with ... -
Genetic control of agronomic traits in an oat population of recombinant lines
(2010) [Artículo de periódico]Understanding the genetic control of phenotypic traits is essential to increase the efficiency of selection for adapted, high-yielding genotypes. The purpose of this study was to determine the genetic control of nine traits ... -
Genetic counseling and presymptomatic testing programs for Machado-Joseph Disease : lessons from Brazil and Portugal
(2014) [Artículo de periódico]Machado-Joseph disease (MJD) is an autosomal dominant, late-onset neurological disorder and the most common form of spinocerebellar ataxia (SCA) worldwide. Diagnostic genetic testing is available to detect the disease-causing ... -
Genetic differentiation in East African ethnicities and its relationship with endurance running success
(2022) [Artículo de periódico]Since the 1960s, East African athletes, mainly from Kenya and Ethiopia, have dominated long-distance running events in both the male and female categories. Further demographic studies have shown that two ethnic groups are ... -
Genetic divergence among interspecific Paspalum hybrids based on seed production traits
(2017) [Artículo de periódico]The use of genetic divergence as a basis for identifying superior individuals, with greater heterozygosity, is important in view of the difficulty when selecting of dissimilar genotypes exhibiting high average for interest ... -
Genetic diversity analysis of two Eucalyptus species using ISSR markers
(2020) [Artículo de periódico]Here, we deployed a genetic diversity analysis using ISSR markers in two Eucalyptus species, as a fundamental step toward breeding strategies. The selected species were Eucalyptus urophylla and Eucalyptus microcorys, both ... -
Genetic Diversity and Connectivity of Southern Right Whales (Eubalaena australis) Found in the Brazil and Chile–Peru Wintering Grounds and the South Georgia (Islas Georgias del Sur) Feeding Ground
(2020) [Artículo de periódico]As species recover from exploitation, continued assessments of connectivity and population structure are warranted to provide information for conservation and management. This is particularly true in species with high ... -
Genetic diversity and conservation of Herbertia zebrina deble (Tigridieae: Iridoidea: Iridaceae), an endemic species of south american grasslands
(2017) [Tesis]Frente à intensa perda de habitats naturais em decorrência do uso da terra, faz-se necessário o conhecimento prévio sobre a biologia de populações das espécies para a realização de manejo adequado e criação de estratégias ... -
Genetic diversity and population structure of naturally rare Calibrachoa species with small distribution in southern Brazil
(2019) [Artículo de periódico]Calibrachoa is a South-American genus comprising 27 species, several considered endemic or rare; few were subjects in genetic studies. We attempted to generate new data about the phylogenetically related and rare species ... -
Genetic diversity and population structure of Vriesea reitzii (Bromeliaceae), a species from the Southern Brazilian Highlands
(2018) [Artículo de periódico]The Southern Brazilian Highlands are composed by a mosaic of Mixed Ombrophilous Forest (MOF) and grassland formations, an interesting landscape for the study of population structure. We analyzed the genetic diversity within ... -
Genetic diversity and relatedness within and between species of the genus Oligoryzomys (Rodentia; Sigmodontinae)
