Genetic background of behavior traits in lactating sows under heat-stress conditions and their relationship with heat tolerance and maternal performance traits

open access: yesFrontiers in Genetics
Heat stress is among the most significant welfare challenges facing modern swine production systems worldwide. Pigs are particularly susceptible to heat stress due to their inactive sudoriferous glands, which limits their capacity for evaporative cooling.

The withdrawal from oncogenetic counselling and testing for hereditary and familial breast and ovarian cancer. A descriptive study of an Italian sample [PDF]

open access: yes, 2008
Background. Oncogenetic counselling is seldom followed through, even when individuals are eligible according to the test criteria. The basic variables which influence the decision to undergo the genetic counselling process are: risk perception, expected ...

Contribution of different yield components for grain yield improvement in Maize (Zea mays L.) [PDF]

open access: yesElectronic Journal of Plant Breeding, 2012
Seventy two maize (Zea mays L.) hybrids along with their parental lines were assessed for genetic correlation among 14quantitative traits. All the traits studied exhibited a positive and significant correlation with grain yield except days to tasselling ...

Variability of fibre quality on Chinese Alashan Left Banner White Cashmere goat

open access: yesItalian Journal of Animal Science, 2018
The heritability and the phenotypic and genetic correlations of down weight (DW), down fibre diameter (DFD), and coefficient of variation of the down fibre diameter (CVDFD) of Chinese Alashan Left Banner White Cashmere goat were estimated on 1375 one ...

Avaliação genética do crescimento de bovinos Nelore Mocho, por meio de modelos de multicaracterísticas

open access: yesRevista Ceres
RESUMO Objetivou-se, com este trabalho, estimar parâmetros genéticos para características do crescimento de animais da raça Nelore Mocho. Foram utilizados pesos corporais (Kg) ajustados aos 205 (P205), 365 (P365) e 550 (P550) dias.

Planar compact array with parasitic elements for MIMO systems [PDF]

open access: yes, 2011
A compact planar array with parasitic elements is studied to be used in MIMO systems. Classical compact arrays suffer from high coupling which makes correlation and matching efficiency to be worse.

A COMPARISON OF GENETIC AND PHENOTYPIC CORRELATIONS [PDF]

open access: yesEvolution, 1988
Genetic variances and correlations lie at the center of quantitative evolutionary theory. They are often difficult to estimate, however, due to the large samples of related individuals that are required. I investigated the relationship of genetic- and phenotypic-correlation magnitudes and patterns in 41 pairs of matrices drawn from the literature in ...

Phenotypic plasticity of Myzus persicae (Hemíptera: Aphididae) raised on Brassica oleracea L. var. acephala (kale) and Raphanus sativus L. (radish)

open access: yesGenetics and Molecular Biology, 2003
The study of variability generated by phenotypic plasticity is crucial for predicting evolutionary patterns in insect-plant systems. Given sufficient variation for plasticity, host race formation can be favored and maintained, even simpatrically.
