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 was raised with this idea of hard work and keeping doors open. To be able to choose what you want to do in the future. That was what we tried to tell our children, too.

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

At the time I finished high school, I was determined to study biology, deeply convinced to eventually be a researcher.

I think women who are pretty certainly have an advantage in any field, in any profession. When a girl is born people still say: Oh, I'm glad that she is pretty. They don't look at whether she is intelligent.

The pressure on kids is high to get good grades. In my time, no one cared about it. My father looked at them but he didn't really make much fuss about them.
