This is one given problem on my homework assignment for developmental biology. Thank you for the help!Describe the effects of FGF and RA on each other in limb bud development. Give a specific example of their effects on each other in this capacity. Knowing this, propose a question/hypothesis to investigate the mechanism of how a specific morphogen controls pattern if you know that the morphogen is both necessary and sufficient AND is expressed in the correct spatial/temporal frame.
The 48-hr Chick Embryo Whole Mount (SEE IMAGE) Before you mount your slide on your microscope stage, take a good look at the morphology of the 48-hour embryo. Note the striking changes in morphology as compare, to the 33-hour embryo. There is a cephalic flexure or bending at the level of the midbrain. The head now lies on its left side. On the other hand dorsal side of the trunk is still turned up so the twisting of the embryo is noticeable. Verify these changes under the low power objective. Note the flexion and the torsion. In addition to the cranial/cephalic flexure there is also a cervical flexure at the level of the neck region. Very briefly go through the structures previously seen in the 33-hour chick. Observe the new structures appearing for the first time (Please visit the main website for viewing the whole mount of 33-hour and 48-hour chick embryo).

Congenital and Genetic Disorders Pamela is age 43 and had declined the offer of having an amniocentesis during pregnancy. The basic routine ultrasound results and other prenatal examinations indicated normal fetal development. However, following delivery, the physical characteristics of Down syndrome became apparent. Twenty-four hours after delivery, the infant showed signs of heart failure related to a ventricular-septal defect and was scheduled for surgical repair of the defect. What specific type of disorder is Down syndrome? Would amniocentesis have indicated that the fetus had Down syndrome? Explain. Down syndrome may be caused by genetic anomalies? What are they? Explain how these anomalies are formed and the mechanism of how they are able to cause Down syndrome? (Support your answer with 9 possible outcomes) Based on the tests performed, could the ventricular-septal defect have been detected before the infant was delivered? Explain your reasoning. What would…
