Summary Introduction

To review:

Each parent is able to contribute only a single allele of each gene to his/her offspring, rather than both alleles.

Introduction:

According to Mendel's law, each individual has two factors for each trait one of which they get from each parent. Depending on the type of information they get from their parents, they are divided into two categories: homozygous and heterozygous. An individual is said to be homozygous for the trait if it is carrying identical factors. If the two different factors have different information then the individual is said to be heterozygous. Alternative forms of a factor called as alleles. An individual contains two alleles for each trait, one from each parent (that is one from female and one from male parent).

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.
