Genetic variability in Halobacterium halobium [PDF]

open access: yesJournal of Bacteriology, 1981
Halobacterium halobium exhibits an extraordinary degree of spontaneous variability. Mutants which are defective in the formation of gas vacuoles (vac) arise at a frequency of 10(-2). Other easily detectable phenotypes, like the synthesis of bacterioruberin (Rub) or the synthesis of retinal (Ret) and bacterio-opsin (Ops), the two components which form ...

Prediction of breeding values and selection responses with genetic heterogeneity of environmental variance [PDF]

open access: yes, 2007
There is empirical evidence that genotypes differ not only in mean, but also in environmental variance of the traits they affect. Genetic heterogeneity of environmental variance may indicate genetic differences in environmental sensitivity.

Genetic variability in the cholecystokinin A receptor affects lipid profile and glucose tolerance in patients with polycystic ovary syndrome

open access: yes, 2022
Introduction Cholecystokinin (CCK) is involved in several metabolic pathways, and CCK agonists are considered as a potential novel treatment option in populations with increased metabolic risk, including polycystic ovary syndrome (PCOS).

Genetic Variables That Influence Phenotype [PDF]

open access: yesILAR Journal, 2006
Characterization of genetically engineered mice requires consideration of the gene of interest and the genetic background on which the mutation is maintained. A fundamental prerequisite to deciphering the genetic factors that influence the phenotype of a mutant mouse is an understanding of genetic nomenclature.

Tumour SNPs Associated with Immune-Related Hepatitis in Patients with Melanoma Receiving Immune Checkpoint Inhibitors

open access: yesBiomedicines
Background and Aims: Immune checkpoint inhibitors (ICIs) have significantly improved survival rates for patients with metastatic melanoma. However, these treatments can lead to immune-related adverse events (irAEs), including hepatitis.

Genetics and Variable Drug Response [PDF]

open access: yesJAMA, 2011
Annual health care expenditures currently exceed $2.5 trillion in the United States, a cost burden equivalent to more than $8000 per person per year. Treatment strategies designed to optimize efficacy, ie, avoiding therapeutic failure while minimizing toxicity, hold the potential to reduce this cost burden.

Patterns of morphological and genetic variability in UK populations of the shore crab, Carcinus maenas Linnaeus, 1758 (Crustacea: Decapoda: Brachyura)

open access: yes, 2006
Previous research has identified extensive inter-population variability in the morphology of the shore crab (Carcinus maenas L.). To determine the source of this variation (genetic or environmental), morphological and genetic data were analysed from ...

Evaluation of genetic parameters of agro-morpho-quality traits in American cotton (Gossypium hirsutum L.)

open access: yesElectronic Journal of Plant Breeding, 2020
In the present study, forty American cotton (Gossypium hirsutum L.) genotypes of diverse origin were evaluated to observe the genetic variability, heritability and genetic advance for yield and fibre quality traits.
