Q.1) Do homeotic genes specify the anterior-posterior or the dorsal-ventral differences? 

Q.2) What is more conserved: regulatory DNA or regulatory proteins? 

Q.3) What is asymmetrically distributed during an asymmetric cell division (DNA or cytoplasmic molecules)? 

Q.4) How do cells get the morphogen inside if the morphogen is a transcription regulator? 

Q.5) Give examples of signaling molecules involved in inductive signaling during development 

Q.6) Does a larva have segments, or just an adult fly? 

Q.7) Are the posterior and the anterior ends predetermined before fertilization? Are the dorsal and the ventral sides predetermined? 

Q.8) What are the factors, determining the egg polarity? Are they coded by mother or zygote genes? 

Q.9) Which protein segmental expression pattern persists throughout the life? 

Q.10) What is the Hox complex? 

Q.11) Are homeotic genes expressed according to their order in the genome? 

Q.12) What is the positional memory of an imaginal disc? 

Thank you so much!!! :D
