A Model for the Generation and Transmission of Variations in Evolution [PDF]

open access: yes, 2013
The inheritance of characteristics induced by the environment has often been opposed to the theory of evolution by natural selection. Yet, while evolution by natural selection requires new heritable traits to be produced and transmitted, it does not ...

Genotype-phenotype correlations in tuberous sclerosis [PDF]

open access: yesJournal of Medical Genetics, 2000
Editor—Van Slegtenhorst et al 1 reported a mutational analysis of 225 patients with tuberous sclerosis (TSC) and concluded that there was no evidence for genotype-phenotype correlation. At virtually the same time, Jones et al 2 from Cardiff published supportive evidence for genotype-phenotypic correlation in their comprehensive mutational analysis of ...

Comprehensive genotype-phenotype correlation in lissencephaly

open access: yesQuantitative Imaging in Medicine and Surgery, 2018
Malformations of cortical development (MCD) are a heterogenous group of disorders with diverse genotypic and phenotypic variations. Lissencephaly is a subtype of MCD caused by defect in neuronal migration, which occurs between 12 and 24 weeks of gestation.

Genetic distance predicts trait differentiation at the subpopulation but not the individual level in eelgrass, Zostera marina. [PDF]

open access: yes, 2018
Ecological studies often assume that genetically similar individuals will be more similar in phenotypic traits, such that genetic diversity can serve as a proxy for trait diversity.

Interrelationship and cause effect analysis among panicle yield attributing traits in lowland Traditional Rice [PDF]

open access: yesJournal of Central European Agriculture, 2014
Yield component analysis provides a framework for identifying potentially useful traits for yield improvement. A field experiment was conducted for two consecutive years to evaluate the forty four low land traditional rice cultivars for twenty three ...

A Multinational Analysis of Mutations and Heterogeneity in PZase, RpsA, and PanD Associated with Pyrazinamide Resistance in M/XDR Mycobacterium tuberculosis. [PDF]

open access: yes, 2017
Pyrazinamide (PZA) is an important first-line drug in all existing and new tuberculosis (TB) treatment regimens. PZA-resistance in M. tuberculosis is increasing, especially among M/XDR cases.

A tractable genotype-phenotype map for the self-assembly of protein quaternary structure

open access: yes, 2013
The mapping between biological genotypes and phenotypes is central to the study of biological evolution. Here we introduce a rich, intuitive, and biologically realistic genotype-phenotype (GP) map, that serves as a model of self-assembling biological ...

Possibilities and limitations of vegetative propagation in breeding and mass propagation of Norway spruce [PDF]

open access: yes, 2003
The use of vegetative mass propagation in practical forestry with Norway spruce (Picea abies (L.) Karst.) is limited at present, although its potential to deliver high genetic gains is obvious.

Mismatches between the genetic and phenotypic sex in the wild Kou population of Nile tilapia Oreochromis niloticus [PDF]

open access: yes, 2019
Sex determination and sex chromosomes can be very diverse between teleost species. The group of tilapias shows a polymorphism in sex determination not only between closely related species but also between domestic strains within a species.
