Summary Introduction

Introduction:

The human heart has four-chambers: right atrium, left atrium, right ventricle and left ventricle. The circulation in which oxygen is absorbed by the blood and carbon dioxide is released at the lungs followed by the return of blood to the heart is termed as pulmonary circulation while in the systemic circulation, blood transfers oxygen to complete body and collects carbon dioxide from cells before coming back to the heart. This type of circulation is known as double circulation.

If using animals in medical experiments could save human lives, is it ethical to do so? In your answer, apply at least one ethical theory in support of your position.
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.
