One of the main goals of selection schemes in beef cattle populations is to increase carcass weight at slaughter. Live weights at different growth stages are frequently used as selection criteria under the hypothesis that they usually have a high and positive genetic correlation with weight at slaughter. However, the presence of compensatory growth may bias the prediction ability of early weigh...

Abstract Drought events may reduce growth and survival of conifer trees. The effects the intensity timing drought on resilience, including reductions during recovery after drought, remain, however, highly uncertain. Growth resilience 20 species to 11 dry years was compared in a common garden experiment. We assessed (a) relationships among resistance, (b) impacts different dimensions (intensity,...

Growth hormone (GH) has an effect on a broad variety of physiological parameters such as lactation, reproduction, growth and metabolism. Thus, the aim of this study was to detect GH gene polymorphism and its association with breeding values of production and reproduction traits in Raini Cashmere goat. Breeding values were estimated using records on 26731 Raini Cashmere goats. To study GH gene p...

Based on a comprehensive study of 100 samples safflower from the world gene pool for three years, results selection primary sources different areas (growth period, 1 plant yield, 1000 seed weight, oil content) are covered. Primary have been identified basis early maturity samples, size, content in seeds, correlation between complex traits and main economic traits. Correlation major crop charact...

Genetic parameters from a second generation (F 2) disconnected diallel progeny test of the New Zealand radiata pine improvement progamme are presented. Heritability estimates of growth and yield traits of 0.2 are similar to progeny test results of the previous generation (F 1). Coefficients of variation for additive genetic and phenotypic variances are also similar between generations. Quality ...

The genetic and developmental bases for trait expression and variation in adults are largely unknown. One system in which genes and cell behaviors underlying adult traits can be elucidated is the larval-to-adult transformation of zebrafish, Danio rerio. Metamorphosis in this and many other teleost fishes resembles amphibian metamorphosis, as a variety of larval traits (e.g., fins, skin, digesti...
