Summary Introduction

To determine:

The number of chromosomes in a mule, which is produced by a cross between a horse having 64 chromosomes and a donkey having 62 chromosomes. Also describe the reasons for the fact that most mules are sterile.

Introduction:

Chromosomes are the threadlike structure present in the nucleus of the cells of an organism. A Chromosome carries the genetic material and a packaging protein. They have an X-shaped structure and the two arms of chromosomes called as sister chromatids joined at the region called the centromere. Horses have 64 numbers of chromosomes and a donkey has 62 numbers of chromosomes.

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.
