Question
Chapter 24.4, Problem 2CC
Summary Introduction
To predict: The effect of the expression of Drosophila’s eyeless gene on the tip of the mouse’s tail.
Introduction: The Pax6 (paired box) is a transcription factor protein-encoding gene that controls the regulation of expression of many different genes. This gene is known to coordinate the development of the eye in rats and humans. Any mutation in the gene can cause underdevelopment leading to small eyes.

- Figure 13-7 illustrates the expression of the Ultrabithorax(Ubx) Hox protein in developing flight appendages.What is the relationship between where the protein isexpressed and the phenotype resulting from the loss ofits expression (shown in Figure 13-1)?arrow_forwardIt 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_forwardExplain hoxA3 and HoxD3 genes are nearly equivalent yet they play distinct roles in the development of mouse.arrow_forward
