The number of genes that are necessary to specify a complete developmental network for a fruit fly. Introduction: It is observed that developmental genetics depends on the regulation and expression of a complex network of genes through transcription factors. In Drosophila , such a network is seen to regulate the body plan and the morphological structures of the organism.

You have identified a Drosophila gene that is expressed exclusively in the odd-numbered "stripes" in the cellular blastoderm. Assuming that this gene is not redundant, what would be the most likely phenotype cause by a loss-of-function mutation in this gene? an embryo missing odd numbered segments an adult fly with a second pair of wings instead of halteres an embryo with two anterior ends an embryo missing even-numbered segments an embryo missing larval segments 3-10

Name three possible factors contributing to early asymmetries in a developing embryo (i.e. what are the kinds of things early on that lead to the development of the body axes - dn, a/p, l/r, etc)? In the fruit fly drosophila melanogaster, the anterior-to-posterior body axis becomes segmented into distinct regions. explain the role of the genes bicoid and nanos in this process.

What changes, if any, would you predict would occur in the pigmentation of Drosophila melanogaster with increased global warming? What type of genetic changes would you expect to see? Be as specific as you can.
