Chapter 15, Problem 2AA
Summary Introduction

To explain: The reason why reproductive isolation is a critical component of speciation.

Concept introduction:  Speciation occurs between reproductive barriers and between the isolated population and its parent population. Speciation is an evolutionary process by which the lineages split into new or distinct species. Reproductive isolation is achieved through the reproductive barriers that are the evolutionary mechanism or behaviors that prevent organism of different species from breeding.

Summary Introduction

To explain: The relationship between gene flow and speciation.

Concept introduction:  Speciation is an evolutionary process by which the lineages split into new or distinct species.

Summary Introduction

To explain: The evolutionary factors that play in the process of speciation.

Concept introduction:  Speciation is an evolutionary process by which the lineages split into new or distinct species. Gene flow is the exchange of alleles within or out of the population caused by movement of fertile individuals or their gametes.

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.
