..., distribution and reproduction in any medium provided that the original work is properly attributed. Eye Development Drosophila Morphogen Growth Models Biophysics For many years, Drosophila imaginal discs have been a model system of choice to study genetic mechanisms of patterning...

...Hans Meinhardt ABSTRACT Models of pattern formation and possible molecular realizations are discussed and compared with recent experimental observations. In application to the dorsoventral patterning of insects, it is shown that a superposition of two pattern-forming reactions is required...

...Hans Meinhardt ABSTRACT Recent experiments concerned with early Drosophila development require some modification of models proposed earlier. The addition of a positional information system spreading out from the anterior pole (as indicated by the bicoid mutation) allows very good size regulation...

... very rarely affected, and disrupted regions rarely started in the middle abdomen (segments A5 and A6). The results are discussed in relation to two models (the clock and wavefront and progress zone models) that have been proposed as an explanation for the specification of the somite pattern...
