Web28 apr. 2016 · Using experimental evolution, studies with Drosophila have tested how acclimation, hardening, and selection for survival and reproduction—in both moderate and extreme cold and heat—influence thermal tolerance. Models of thermal adaptation generally assume that selection for thermal tolerance breadth (or cold or heat tolerance) has … WebMarker-assisted selection or marker aided selection (MAS) is an indirect selection process where the desired trait is selected based on a marker (morphological, biochemical or DNA/RNA variation) linked to a trait of interest (e.g. productivity, disease resistance, tolerance, and quality), rather than on the trait itself.
