Summary Introduction

To analyze:

The end-Permian species (underwent devastating extension) is compared to a graduation class with 1800 students, to determine the number of students that would exist by the end of the graduation if this class represents the Permian extinction era.

Introduction:

The term Permian denotes a geologic period, which ranged over 47 million years from the Carboniferous end. During Permian, early amniotes diversified into turtles, mammals, archosaurs, and lepidosaurs. The Permian period ended during the Permian-Triassic event, with the extinction of many terrestrial and marine species.

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.
