Summary Introduction

To determine: Thematrix of six animal species showing different vertebrate characters.

Introduction: The phylum chordate contains various divisions and among them the vertebrate forms a significant category. The division vertebrate contains Reptilia, Pisces, Amphibia, Mammalia, and Aves. The advanced animals evolved from Pisces and continued through amphibian, reptiles, birds to mammals.

Table 1: The matrix of six animal species showing different vertebrate characters.

Embryonic development is a complicated process where a vast number of genes and signaling methods are required to accurately form the differentstructures of the growing fetus. The chordates share a large number of characteristics with the deuterostomes that indicate the origin of the chordates from the deuterostomes.

The features common to both deuterostomes and chordates include the presence of radial cleavage, first embryonic opening forming the anus. The vertebrates share unique characters that demarcate them from invertebrates and these include presence of hair, tail, and amniotic sac, which is not present in invertebrates.

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.
