Morphogens play a key role in development, cre-ating concentration gradients that inform cells of wherethey are and how to behave. Examine the simple patternsrepresented by the flags in Figure Q21–1. Which do yousuppose could be created by a gradient of a single mor-phogen? Which would require gradients of two morpho-gens? Assuming that such patterns were present in a sheetof cells, explain how they could be created by morphogens.
Researchers in search of loci in the human genome that arelikely to contribute to the constellation of factors leading tohypertension have compared candidate loci in humans and rats[Stoll, M., et al. (2000). New Target Regions for Human Hypertensionvia Comparative Genomics. Genome Res. 10:473–482].Through this research, they identified 26 chromosomal regionsthat they consider likely to contain hypertension genes. Howcan comparative genomics aid in the identification of genesresponsible for such a complex human disease? The researchersstate that comparisons of rat and human candidate loci tothose in the mouse may help validate their studies. Why mightthis be so?
The origin of new β cells of the pancreas—fromstem cells or from preexisting β cells—was not resolveduntil a decade ago, when the technique of lineage tracingwas used to decide the issue. Using transgenic mice thatexpressed a tamoxifen-activated form of Cre recombinaseunder the control of the insulin promoter, which is activeonly in β cells, investigators could remove an inhibitorysegment of DNA and thereby allow expression of humanplacental alkaline phosphatase (HPAP), which can bedetected by histochemical staining. After a pulse of tamox-ifen that converted about 30% of β cells in young mice to cells that express HPAP, the investigators followed the per-centage of labeled β cells for a year, during which time thetotal number of β cells in the pancreas increased by 6.5-fold. How do you suppose the percentage of β cells wouldchange over time if new β cells were derived from stemcells? What if new β cells were derived from preexistingβ cells? Which hypothesis do the results in Figure…

A research paper published in the summer of 2012presented a method to obtain the whole-genome sequence of a fetus without any invasive procedure suchas amniocentesis that could on rare occasions causemiscarriage. This new technique is based on the factthat some fetal cells leak into the mother’s bloodstream and then break down, releasing their DNA.Assume that exactly 10% of the DNA fragments inthe mother’s blood serum come from the fetus, whilethe remaining 90% of the DNA fragments in the serum come from the mother’s genome.The investigators collected cell-free DNA from apregnant woman’s bloodstream and subjected it to anadvanced high-throughput sequencing method. Thetable at the end of this problem looks at seven unlinked loci; the number of reads of particular alleles(identified by Greek letters) are shown. You shouldassume for the sake of simplicity that all numericaldifferences are statistically significant (even thoughactual data are never this clean).a. Determine whether each…

Mouse models for human genetic diseases are potentially powerful tools to help geneticists understand thecause of the aberrant phenotypes and develop newtherapeutic measures. However, such mice are not always as useful to investigators as it might seem at firstglance. Suppose that you have a mouse knockoutmodel for a human disease caused by homozygosityfor a null allele of a gene. Discuss how the followingsituations might complicate investigations of the human disease based on this mouse model.a. Mice have a shorter life span than humans.b. Mice homozygous for certain knockout mutationsdie in utero.c. Mouse genomes may have additional copies of thegene whose mutation causes the disease in humans.d. Mice from different inbred lines homozygous forthe same gene knockout vary in the penetrance andexpressivity of the phenotype.e. Manipulations to create the knockout mouse, suchas the presence of a drug resistance gene that allowsthe selection of cells containing the knockout (seeFig. 18.9),…
