Question
Chapter 17.2, Problem 1C
Summary Introduction
To describe: The relative merits of Drosophila melanogaster, Caenorhabditis elegans, Mus musculus, and Arabidopsis thaliana those have made these organisms valuable models in developmental genetics.
Introduction: The growth and development of an organism is controlled by genes. Developmental genetics gives us insight on how these genes influence the growth and development of an organism. The patterns of morphogenesis in different species are investigated. Information necessary to build an organism is passed in the form of genes from one generation to the next.

- Compare and contrast the experimental advantages and disadvantages of Drosophila, C. elegans, mammals, and Arabidopsis.arrow_forwardHow have we discovered that specific genes control development in an organism like Drosophila?arrow_forwardprovide one example from the Drosophila AP toolkit for "Toolkit genes can be classified according to the phenotypes caused by their mutation. Similar mutant phenotypes often reflect genes that function in a single developmental pathway. Distinct pathways exist for the generation of body axes, for example, and for the formation and identity of fields."arrow_forward
- With regard to development, what are the roles of the maternaleffect genes versus the zygotic genes? Which types of genes are needed earlier in the development process?arrow_forwardUsing Figure 22.6, indicate the stage at which segmentation genes, homeotic genes, and egg-polarity genes would have an effect on development.arrow_forwardName 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.arrow_forward
- It seems that developmental genetics boils down to a complex network of gene regulation. Try to draw a structure of this network for Drosophila. How many genes do you think are necessary to complete the developmental network for the fruit fly? How many genes do you think are needed for a network to specify one segment? Do you think it is more difficult to identify genes that are involved in the beginning, middle, or end of this network? Suppose you were trying to identify all of the genes needed for development in a chicken. Knowing what you know about Drosophila development, would you first try to identify genes necessary for early development, or would you begin by identifying genes involved in cell differentiation?arrow_forwardDiscuss the role of homeotic genes in development. Explain what happens to the phenotype of a fruit fly when a gain-of-function mutation in a homeotic gene causes the protein to be expressed in an abnormal region of the embryo. What are the consequences of a loss-of-function mutation in such a gene?arrow_forwardCompare and contrast how maternal-effect genes, gap genes, and homeotic genes affect Drosophila development.arrow_forward
- Give examples of genes that affect development in fruit flies by regulating gene expression at the level of (a) transcription and (b) translation.arrow_forwardThe anterior–posterior axis of a Drosophila embryo is first established by certain (a) homeotic genes (b) maternal effect genes (c) segmentation genes (d) proto-oncogenes (e) pair–rule genesarrow_forwarda) Do the loss of function phenotypes differ between the genes between the genes in figure 1? What does this mean? b) What are the two cell types responsible for producing maternal gene products involved in terminal patterning in the Drosophila cocyte? In which of these two cell types is each of the three genes expressed? c) Based on the phenotypes you observed for the three genes, and on the differences in their expression patterns, which one of the genes do you think is the localised determinant of terminal patterning? d❘ From the gain-of-function experiments, do trunk and torso like work upstream or downstream of torso? Explain. (4 m e) How might you test which of the trunk and torso-like genes acts upstream of the other? f) The torso gene has been shown to have another important role in Drosophila development outside of terminal patterning. What do you think would be a good first experiment to do to begin to investigate possible other roles for the trunk or torso - like genes? C a…arrow_forward
