Summary Introduction

To review:

The theory of the evolution by natural selection to fulfill these six criteria.

(1) They explain otherwise puzzling observations;

(2) They provide connections between otherwise disparate observations;

(3) They make predictions that can be tested; and

(4) They are heuristic, meaning that they open up new avenues of theory and experimentation. Crow added two other elements of scientific theories that he considered important on a personal, emotional level.

(5) They should be elegant, in the sense of being simple and powerful;

(6) They should have an element of surprise

Introduction:

The theory of the evolution was first formulated in 1859 and it was defined as a process through which the organism alters over a period of time due to the result of changes in the heritable traits (physical or behavioral).

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.
