Drosophilla wing development Flashcards
1
Q
What do adult organs in drosophila derive from?
A
Imaginal Discs
2
Q
What type of polarity does drosophila wing disk exhibit?
A
Dorsal ventral and anterior posterior
3
Q
How is their a strict boundary between the anterior and posterior regions of the wing disc?
A
Because the anterior and posterior cells come from different cell lineages
4
Q
What is engrailed?
A
Engrailed is a TF which is expressed in posterior cells.
It promotes the expression of hedgehog but inhibits the expression of patched and ci
5
