Energy and Arginine Density in the Diets of Arbor Acre Hens from 40 to 50 Weeks of Age: Effects on Development and Lipid Metabolism of Embryos

open access: yesAnimals, 2023
The effects of maternal dietary energy and arginine level on embryonic development and serum lipid metabolism were investigated in this study. A 2 × 3 factorial experiment was conducted with six treatments represented by 10 replicates of eight Arbor Acre

Exploiting combining ability and maternal effects for genotypic selection of best hybrids in sweet corn and normal corn crosses

open access: yesElectronic Journal of Plant Breeding, 2021
Twenty one sweet – normal corn crosses and twenty one normal – sweet corn crosses obtained by [3 × 7] sweet corn × normal corn and [7 × 3] normal corn × sweet corn crosses, respectively were scrutinized for the advantage of reciprocal cross effects in ...

The Evolution of Multivariate Maternal Effects

open access: yesPLoS Computational Biology, 2014
There is a growing interest in predicting the social and ecological contexts that favor the evolution of maternal effects. Most predictions focus, however, on maternal effects that affect only a single character, whereas the evolution of maternal effects is poorly understood in the presence of suites of interacting traits. To overcome this, we simulate

Effects of Nutritional Restriction during Laying Period of Fat and Lean Line Broiler Breeder Hens on Meat Quality Traits of Offspring

open access: yesAnimals, 2021
The offspring meat quality of hens undergoing a 25% dietary restriction treatment during the laying period were evaluated in fat and lean line breeder. A total of 768 female birds (384/line) were randomly assigned to four groups (12 replicates/group, 16 ...

Comparative analysis of maternal and grand-maternal photoperiodic responses of Trichogramma species (Hymenoptera: Trichogrammatidae)

open access: yesEuropean Journal of Entomology, 2013
Maternal and grand-maternal photoperiodic responses of Trichogramma buesi, T. embryophagum, T. evanescens, T. piceum, T. principium, and T. telengai were investigated in laboratory conditions.

Maternal Effects in Molecular Evolution [PDF]

open access: yesPhysical Review Letters, 2002
We introduce a model of molecular evolution in which the fitness of an individual depends both on its own and on the parent's genotype. The model can be solved by means of a nonlinear mapping onto the standard quasispecies model. The dependency on the parental genotypes cancels from the mean fitness, but not from the individual sequence concentrations.

Interactions Between Maternal, Paternal, Developmental, and Immediate Environmental Effects on Anti-predator Behavior of the Snail Physa acuta

open access: yesFrontiers in Ecology and Evolution, 2020
Transgenerational plasticity, which occurs when the environment experienced by parents changes the phenotype of offspring, is widespread in animal and plant species.

Efeito da herança citoplasmática sobre características de produção em ovinos da raça merino Effects of cytoplasm inheritance on production traits of merino sheep

open access: yesRevista Brasileira de Zootecnia, 1999
Para avaliar os efeitos de linhagem citoplasmática (LCT), foram usadas medidas de peso corporal (PC, n = 707) e peso de velo sujo (PVo, n = 703) de fêmeas e medidas de diâmetro das fibras de lã (DF, n = 350) de machos ovinos da raça Merino com um ano de ...

Avaliação genética multirracial para ganho de peso pré-desmama em bovinos de uma população composta Multibreed genetic evaluation for pre-weaning daily gain in a composite cattle population

open access: yesRevista Brasileira de Zootecnia, 2008
Objetivou-se neste trabalho estudar modelos com efeitos não-aditivos diretos e maternos em uma população composta em clima tropical, tentando minimizar esses efeitos para obtenção dos valores genéticos dos animais avaliados.
