Summary Introduction

To explain: The contribution to the development of the phenomenon of speciation from the learned behavior.

Concept introduction: The speciation and development of fledglings of birds include the designing of experiments in which different songs are played near the fledglings. They get oriented towards the songs, but are not allowed to hear the real bird sounds and voices, for example in the white-crowned sparrow. The fledglings then learn the songs from the group of birds, which gets imprinted in their memory and they recognize it. This song patterns are learned much faster than the artificial songs played during the experiments. This is called as the “learned behavior” in birds.

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.
Design a grafting experiment to determine if limb mesoderm determines forelimb / hindlimb identity. Include the experiment, a control, and an interpretation in your answer.
