ABSTRACT The amount and form of natural genetic variation for recombination were studied in six lines for which second chromosomes were extracted from a natural population of Drosophila melanogaster. Multiply marked second, Χ and third chromosomes were used to score recombination. Recombination in the second chromosomes varied in both amount and distribution. These second chromosomes caused variation in the amount and distribution of crossing over in the Χ chromosome and also caused variation in the amount, but not the distribution, of crossing over in the third chromosome. The total amount of crossing over on a chromosome varied by 12-14%. One small region varied twofold; other regions varied by 16-38%. Lines with less crossing over on one chromosome generally had less crossing over on other chromosomes, the opposite of the standard interchromosomal effect. These results show that modifiers of recombination can affect more than one chromosome, and that the variation exists for fine-scale response to selection on recombination.

Positive Valence

A painful event establishes two opponent memories: cues that are associated with pain onset are remembered negatively, whereas cues that coincide with the relief at pain offset acquire positive valence. Such punishment- versus relief-memories are conserved across species, including humans, and the balance between them is critical for adaptive behaviour with respect to pain and trauma. In the fruit fly, Drosophila melanogaster as a study case, we found that both punishment- and relief-memories display natural variation across wild-derived inbred strains, but they do not covary, suggesting a considerable level of dissociation in their genetic effectors. This provokes the question whether there may be heritable inter-individual differences in the balance between these opponent memories in man, with potential psycho-clinical implications.

Three Components

ABSTRACT This study examines natural genetic variation in density sensitivity of three components of fitness in Drosophila melanogaster using the method of chromosome extraction. Different lines are differentially sensitive to density. The distribution of measures of density sensitivity of chromosomal homozygotes is different from that of random chromosomal heterozygotes for both location and dispersion. Density sensitivity of the components is about as variable as any of the fitness components themselves at fixed densities. The consequences of the exact nature of this density dependence are discussed with respect to the stage of the life cycle at which density dependence occurs, and the mathematical form that it takes. There is no evidence of trade-offs among the components or their density sensitivity.
