Chapter 51, Problem 1COQ
Summary Introduction

To determine: Describe the major events in the animal development beginning with cleavage.

Introduction: The process of embryo development involves cell division, growth, and these cells later migrate in specific patterns to make specific lineage of the cells. There are four initial stages in the early development of an embryo, namely fertilization, cleavage, gastrulation, and organogenesis.

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb?  Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
