Describe the genotypes of people with hemophilia.

answer:

the gene with the instructions for making factor is found only on the sex chromosome labeled x. if the gene is faulty, the result is hemophilia unless there is a dominant, normal gene on a matching x chromosome. hemophilia is a sex-linked recessive disorder. these kinds of defects occur more often in men than in women.

explanation:

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
