Genetic parameters and response to selection for thermal tolerance, summer survival and growth in hybrid oyster (Crassostrea gigas ♀ × C. angulata ♂)

open access: yesAquatic Living Resources, 2023
The Pacific oyster Crassostrea gigas is the most commonly farmed mollusks worldwide, while its production has been hindered by massive mortalities linked to high temperatures.

Combining polynomial chaos expansions and genetic algorithm for the coupling of electrophysiological models [PDF]

open access: yes, 2019
The number of computational models in cardiac research has grown over the last decades. Every year new models with di erent assumptions appear in the literature dealing with di erences in interspecies cardiac properties.

Key Genetic Parameters for Population Management [PDF]

open access: yesFrontiers in Genetics, 2019
Population management has the primary task of maximizing the long-term competitiveness of a breed. Breeds compete with each other for being able to supply consumer demands at low costs and also for funds from conservation programs. The competition for consumer preference is won by breeds with high genetic gain for total merit who maintained a ...

Estimates of covariance functions for growth of Anglo-Nubian goats Estimativas de funções de covariância para crescimento de caprinos anglo nubianos

open access: yesRevista Brasileira de Zootecnia, 2011
It was used 4,313 weight records from birth to 196 days of age from 946 Anglo-nubiana breed goats, progenies from 43 sires and 279 dams, controlled in the period from 1980 to 2005, with the objective of estimating covariance functions and genetic ...

Genetic Effect and Growth Curve Parameter Estimation under Heat Stress in Slow-Growing Thai Native Chickens

open access: yesVeterinary Sciences, 2021
Heat stress is becoming a major problem because it limits growth in poultry production, especially in tropical areas. The development of genetic lines of Thai native chickens (TNC) which can tolerate the tropical climate with the least compromise on ...

Application of a single-objective, hybrid genetic algorithm approach to pharmacokinetic model building. [PDF]

open access: yes, 2012
A limitation in traditional stepwise population pharmacokinetic model building is the difficulty in handling interactions between model components. To address this issue, a method was previously introduced which couples NONMEM parameter estimation and ...

Estimation of quantitative genetic parameters [PDF]

open access: yesProceedings of the Royal Society B: Biological Sciences, 2008
This paper gives a short review of the development of genetic parameter estimation over the last 40 years. The need to analyse genetic processes in both animal selection experiments and animal breeding improvement programmes motivated the majority of this work.
