Question
Chapter 26.2, Problem 1BC
Summary Introduction
To determine:
If three layers in the Bilateriaa shared derived character or a shared primitive character.
Introduction:
Phylogenetics can be described as the study of the evolutionary history of an organism and its relationship with other
With respect to phylogenetics and systematics, a shared primitive character is that character that is shared by members of a clade, that originated in an ancestor that is not a member of that clade. Shared derived character is that character that has an evolutionary uniqueness that is distinctive to a clade, it is not inherited from ancestors.

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.

- A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.arrow_forwardA sample of blood was taken from the above individual and prepared for haemoglobin analysis.
