Genetic recombination in this organism is prevented by deliberately causing chromosomal inversions to block synapsis.
Genetic recombination in this organism is prevented by deliberately causing chromosomal inversions to block synapsis. A gene family discovered in this organism got its name from the German for "great" after its role in sensing infection was first realized. The P element, a transposon, is found in its genome. This organism replicates its DNA without mitosis to form enormous polytene chromosomes. Its mutants have ironic names like tinman, groucho, and (*) eyeless. Toll-like receptors, the Wnt signaling pathway, and Hox genes were discovered in this organism. Thomas Hunt Morgan had a room devoted to these organisms at Columbia, where he studied genetic linkage in traits like eye color and wing location. For 10 points, name this ubiquitous model insect in biology.
