Chapter 22, Problem 18P

Human geneticists have found the Finnish population to be very useful for studies of a variety of conditions. The population is small; Finns have extensive church records documenting lineages; and few people have migrated into Finland. The frequency of some recessive disorders is higher in the Finnish population than elsewhere in the world, and diseases such as PKU and cystic fibrosis that are common elsewhere do not occur in the Finnish population.

a. How would a population geneticist explain these variations in disease occurrence?
b. The Finnish population is also a source of information for the study of quantitative traits. The genetic basis of schizophrenia is one question that can be explored in this population. What advantage(s) and disadvantage(s) can you imagine for studying complex traits based on the Finnish population structure?

"One of the symmetry breaking events in mouse gastrulation requires the amplification of Nodal on the side of the embryo opposite to the Anterior Visceral Endoderm (AVE). Describe one way by which Nodal gets amplified in this region." My understanding of this is that there are a few ways nodal is amplified though I'm not sure if this is specifically occurs on the opposite side of the AVE.  1. pronodal cleaved by protease -> active nodal 2. Nodal -> BMP4 -> Wnt-> nodal 3. Nodal-> Nodal, Fox1 binding site  4. BMP4 on outside-> nodal  Are all of these occuring opposite to AVE?
