Hormonal pleiotropy structures genetic covariance [PDF]

open access: yesEvolution Letters, 2021
AbstractQuantitative genetic theory proposes that phenotypic evolution is shaped by G, the matrix of genetic variances and covariances among traits. In species with separate sexes, the evolution of sexual dimorphism is also shaped by B, the matrix of between-sex genetic variances and covariances. Despite considerable focus on estimating these matrices,

DNA Variations between Medicago truncatula Symbiotic Mutant Line and Native Variant Using Fluorescence-Based AFLP Marker

open access: yesHighlights in BioScience, 2020
Genetic mutagenesis is a very efficient tool in studying genes function. Because of the great benefits of legumes as human food and animal feed worldwide, we used a model plant Medicago truncatula for identification gene function related to nitrogen ...

SNP Genotyping for Purity Assessment of a Forage Oat (Avena sativa L.) Variety from Colombia

open access: yesAgronomy, 2022
Single nucleotide polymorphism (SNP) markers have multiple applications in plant breeding of small grains. They are used for the selection of divergent parents, the identification of genetic variants and marker-assisted selection.

Genetics of Structural Hair Disorders [PDF]

open access: yesJournal of Investigative Dermatology, 2012
The identification of causative genes carries the promise of new and innovative therapeutic strategies for both inherited and acquired hair disorders. Moreover, the delineation of the relationships between similar phenotypes, resulting from mutations affecting seemingly distinct regulatory pathways, paves the way to improved diagnosis and treatment ...
