Summary Introduction

To review:

Whether multiple pregnancies increase the relative risk of chromosomal defects in offspring.

Introduction:

A study was conducted in Florida during the time span of 1996–2000 on the newborns. This study was conducted on the prevalence of birth defects among the newborns per 10,000 live births. The study also included the prevalence of the defects among multiple and single births. The relative risk was also calculated for each defect. Birth defects are functional or structural abnormalities that are present in a newborn. These may develop either before or at the time of birth.

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.
