Summary Introduction

On earth, there are about 400,000 species of plants are present, surprisingly we consume only a few plants. Those we eat are all angiosperms. The majority of the plants we consume come from species that are grown in cultivation. Some of these cultivated species lost the capability to live and replicate on their own due to artificial selection. Modern agriculture is mainly based on a few species, which exhibits low genetic diversity and also involves in making crops that are vulnerable to microbial pathogen and pests.

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.
