Genetic control and evolution of sexually dimorphic characters in Drosophila.
Kopp A, Duncan I, Godt D, Carroll SB. Kopp A, et al. Nature. 2000 Nov 30;408(6812):553-9. doi: 10.1038/35046017. Nature. 2000. PMID: 11117736
We suggest that bab has an ancestral homeotic function, and that regulatory changes at the bab locus played a key role in the evolution of sexual dimorphism. ...

The roles of hedgehog and engrailed in patterning adult abdominal segments of Drosophila.
Kopp A, Muskavitch MA, Duncan I. Kopp A, et al. Development. 1997 Oct;124(19):3703-14. Development. 1997. PMID: 9367426
We present evidence that hedgehog (hh) protein secreted by posterior compartment cells plays a key role in patterning the posterior portion of the anterior compartment in adult abdominal segments. ...By determining the position of polarity reversal within en-expressing clo …

In an accompanying report (Kopp, A., Muskavitch, M. A. T. and Duncan, I. (1997) Development 124, 3703-3714), we show that Hh protein secreted by posterior compartment cells patterns the posterior portion of the anterior compartment in adult abdominal segments …

Wingless, decapentaplegic and EGF receptor signaling pathways interact to specify dorso-ventral pattern in the adult abdomen of Drosophila.
Kopp A, Blackman RK, Duncan I. Kopp A, et al. Development. 1999 Aug;126(16):3495-507. Development. 1999. PMID: 10409497
Adult abdominal segments of Drosophila are subdivided along the dorso-ventral axis into a dorsal tergite, a ventral sternite and ventro-lateral pleural cuticle. ...

Anteroposterior patterning in adult abdominal segments of Drosophila.
Kopp A, Duncan I. Kopp A, et al. Dev Biol. 2002 Feb 1;242(1):15-30. doi: 10.1006/dbio.2001.0529. Dev Biol. 2002. PMID: 11795937
In this report, we present a detailed description of the expression of four key patterning genes, engrailed (en), hedgehog (hh), patched (ptc), and optomotor-blind (omb), in abdominal histoblasts during the first 42 h after pupariation, a period in which the adult p …

Evolution of male sexual characters in the oriental Drosophila melanogaster species group.

In this report, we apply a new molecular phylogeny to reconstruct the evolution of male sexual characters in a group of species closely related to the model species Drosophila melanogaster. ...More surprisingly, we also find a pervasive pattern of independent …

Quantitative trait loci responsible for variation in sexually dimorphic traits in Drosophila melanogaster.
Kopp A, Graze RM, Xu S, Carroll SB, Nuzhdin SV. Kopp A, et al. Genetics. 2003 Feb;163(2):771-87. Genetics. 2003. PMID: 12618413 Free PMC article.
To capture the pattern of genetic variation present in the wild, a panel of recombinant inbred lines was created from two heterozygous flies taken directly from nature. ...Our results show that at least for some sexually dimorphic traits, a small number of QTL accou …
