Summary Introduction

To analyze:

The chances of having a child with cystic fibrosis for parents who are homozygous normal for it.

Introduction:

Cystic fibrosis is a genetic disorder i.e. it is can be passed on from the parents to the offspring. It is inherited in recessive manner which means that an individual should have two recessive alleles of the gene for being diagnosed with cystic fibrosis. Even if one of the allele is dominant, it will mask the effect of the recessive allele and the phenotype will be normal.

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.
