title: [Analysis of MGE Dm412 localization pattern in Drosophila melanogaster lines undergoing long-term selection for a quantitative character].
abstract: The subpopulation composed of the mixture of Drosophila isogenic lines with interrupted wing radial vein (mutation radius incompletus, ri) was subjected to long-term selection in different directions for increase or decrease in expression of the ri gene. As a result, the lines with contrasting different values of mean character phenotype were developed. The isogenic lines of mean character phenotype were developed. The isogenic lines and F2 from their crosses with selected lines were analysed by the pattern of copia-like MGE DM412 localization. The isogenic lines were shown to have individual pattern, the selected lines differing strongly from them. Selection led to the loss of Dm412 localization sites during negative selection, while positive selection results both in loss and acquisition of sites. Correlation between the phenotype of the quantitative character and the pattern of MGE Dm412 was revealed.
