In systemic searches for embryonic lethal mutants of Drosophila melanogaster we have identified 15 loci which when mutated alter the segmental patterns of the larva. These loci probably represent the majority of such genes in Drosophila. The phenotypes of the mutant embryos indicate that the process of segmentation involves at least three levels of spatial organization: the entire egg as developmental unit, a repeat unit with the length of two segments, and the individual segment.

I think women are just as gifted when it comes to science as men are. But I think their wishes and desires are different and this is also shaped by the society in which they live.

I immediately loved working with flies. They fascinated me, and followed me around in my dreams.

Successful women are not liked. I think the biggest danger for women in science is colleagues who are not as good as you are.

It is very important for me to be taken seriously for my science and not for my looks or other personal accomplishments.

Not everybody is talented for doing research. I think many women prefer to look for an easier job after their dissertations because it is very demanding. You have to be mobile. You have to move to different places for your post-doc training. And if you aren't successful, it isn't a very pleasant job, either.

In my age group I don't know a single woman who is as successful as I am. I am the total exception. You can be very proud of it. But you are also very isolated.
