Direct and Correlated Responses to Selection
Hemolymph juvenile hormone esterase (JHE) activity on the third day of the last stadium in the cricket, Gryllus assirnilis, exhibited a significant response to selection in each of six replicate lines. Mean realized heritability was 0.26 t 0.04. The response was due to changes in whole-organism enzyme activity as well as to changes in the proportion of enzyme allocated to the hemolymph compartm...

15 صفحه اولDirect and Correlated Responses of Selection in Divergent Selection for Intramuscular Fat in Rabbits
The objective of this study was to evaluate the genetic response for a divergent selection experiment on intramuscular fat (IMF) content and to estimate the correlated response in carcass and meat quality traits. Data from two generation of selection were used in this study. The base population was composed of 13 males and 83 females. High (H) and Low (L) lines had 8 males and approximately 40 ...
متن کاملEvolution of starvation resistance in Drosophila melanogaster: measurement of direct and correlated responses to artificial selection.
Laboratory selection for resistance to starvation has been conducted under relatively controlled conditions to investigate direct and correlated responses to artificial selection. With regard to starvation resistance, there are three physiological routes by which the trait can evolve: resource accumulation, energy conservation and starvation tolerance. A majority of energetic compounds and macr...
