A performance test for boar taint compounds in live boars

Animal, 2013
Genetically reducing boar taint using low-taint lines is considered the most sustainable and economic long-term alternative to surgical castration of male pigs.

Phenotypic plasticity for life-history traits in Drosophila melanogaster. III. Effect of the environment on genetic parameters [PDF]

, 2017
We estimated genetic and environmental variance components for developmental time and dry weight at eclosion in Drosophila melanogaster raised in ten different environments (all combinations of 22, 25 and 28°C and 0·5, 1 and 4% yeast concentration, and 0·

Genetic influences on the difference in variability of height, weight and body mass index between Caucasian and East Asian adolescent twins. [PDF]

, 2008
Objective: Twin studies are useful for investigating the causes of trait variation between as well as within a population. The goals of the present study were two-fold: First, we aimed to compare the total phenotypic, genetic and environmental variances ...

Gene Flow, Effective Population Sizes, and Genetic Variance Components in Birds [PDF]

Evolution, 1980
The genetic structure of natural populations is of general interest because many current models in ecology and evolution involve assumptions about the viscosity of breeding populations. For instance, theories of group and kinship selection, local adaptation, and speciation all depend on the magnitude of an among-deme component of genetic variance.

Quantitative inheritance of leaf shape characters in tobacco (Nicotiana tabacum L.) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Plant Science at Massey University, Palmerston North, New Zealand [PDF]

, 1982
An F₁ half diallel cross experiment with 8 parents (i.e. ½ p (p = 1) combinations) was used to study the quantitative inheritance of leaf shape characters in tobacco (Nicotiana tabacum L.).

Genetic architecture of biparental progenies for yi eld in Eggplant (Solanum melongena L.) [PDF]

, 2016
The type of gene action for yield and its components was determined using biparental progenies devel-oped from the F2 generation of an intervarietal cross Swarna Pratibha × Hisar Shyamal (SP × H-8) of eggplant (Solanum melongena L.) using North ...

ESTIMATES OF GENETIC VARIANCE COMPONENT OF AN EQUILIBRIUM POPULATION OF CORN

AGRIVITA Journal of Agricultural Science, 2015
There are abundant maize populations in Hardy-Weinberg equilibrium, which can be used as source of gene to develop either a hybrid variety or an open pollinated variety. Genetic parameters of a population, such as additive genetic variance and variance due to dominance which can be estimated using North Carolina Design I, were used to decide a breeding

Health‐Related Quality of Life and Symptom Severity Among Patients With PIK3CA‐Related Overgrowth Spectrum: A Mixed‐Methods Study to Understand Real‐World Experience With Alpelisib Treatment

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background PIK3CA‐related overgrowth spectrum (PROS) includes several rare overgrowth disorders resulting from somatic gain‐of‐function mutations in PIK3CA. Despite treatment advances, including the recent approval of alpelisib for PROS in the United States, literature detailing the patient experience with PROS is limited.

Genetic Variance and Covariance of the Components of Hatchability in New Hampshires ,

Poultry Science, 1957
Abstract SINCE the early work of Pearl and Surface (1909), a great many studies have been made to determine the extent to which fertility and hatch of fertile eggs are controlled by heredity. Fertility must be considered a property of the parents only, since the trait being studied is no longer fertility once the gametes have united (Bernier, Taylor

‘They Need to Hear You Say It’: Healthcare Professionals’ Perspectives on Barriers and Enablers to End‐of‐Life Discussions With Adolescents and Young Adults With Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT End‐of‐life conversations with adolescents and young adults (AYAs) with cancer rarely occur without the guidance of healthcare professionals. As a part of the ‘Difficult Discussions’ study, focused on palliative care and advance care planning discussions with AYAs with cancer, we investigated the factors that healthcare professionals identify ...
