Genotype by environment interaction for gene expression in Drosophila melanogaster

Phenotypic plasticity and genotype by environment interaction for olfactory behavior in Drosophila melanogaster.

Genotype by environment interactions (GEI) play a major part in shaping the genetic architecture of quantitative traits and are confounding factors in genetic studies, for example, in attempts to associate genetic variation with disease susceptibility. It is generally not known what proportion of phenotypic variation is due to GEI and how many and which genes contribute to GEI. Behaviors are co...

Genotype-environment interaction for quantitative trait loci affecting life span in Drosophila melanogaster.

The nature of genetic variation for Drosophila longevity in a population of recombinant inbred lines was investigated by estimating quantitative genetic parameters and mapping quantitative trait loci (QTL) for adult life span in five environments: standard culture conditions, high and low temperature, and heat-shock and starvation stress. There was highly significant genetic variation for life ...

Genotype environment interaction and fecundity in Drosophila

Genotype-temperature interaction in Drosophila melanogaster. II. Body weight.

The effect of genotype-temperature interactions on body weight has been studied in a natural population of Drosophila melanogaster using four isogenic strains derived from it, and their hybrid F(1) and F(2) progenies. Measurements were made at four constant temperatures-25 degrees , 21 degrees , 17 degrees and 13 degrees C-and at a temperature oscillating between 17 degrees and 25 degrees C.-Lo...

Genetic Structure of Natural Populations Environment Interaction in Viability of Drosophila Melanogaster . Xix . Genotype

To investigate whether or not an excess of additive genetic variance for viability detected in southern natural populations of Drosophila melanogaster was created by diversifying selection, genotype-environment interaction was tested as follows. (1) Two karyotype chromosomes were used: 61 second chromosomes with the standard karyotype and 63 second chromosomes carrying In(2L)t. Their homozygote...
