Question
In Drosophila, expression of the segmentation genes activates the homeotic genes. Expression of the homeotic genes, in turn, determines which adult structures-including antennae, legs, and wings- will form in each of the adult fly's 14 body segments. Part A Two clusters of homeotic genes work together to specify body segment identity during Drosophila development. Expression of these gene products is described as being within parasegments. (Note: The term ''segment'' refers to each outwardly observable and distinct body section, whereas ''parasegment'' refers to regions of gene expression.) Drag the terms to the appropriate blanks to complete the sentences about homeotic genes in Drosophila.Explanation / Answer
Answer :- 1) antennapedia, bithorax.
2) Homeobox, homeodomain protein
3) Hox genes
