How many chromosomes do we expect to light up green

Reference no: EM133291179

Question: A clinical researcher is interested in studying a gene on chromosome 21 and another gene on chromosome X using the FISH technique to locate both genes. The researcher uses fluorescent "probes" of different colors to study both genes simultaneously. Probe A hybridizes with the gene on chromosome 21 and produces a fluorescent green color. On the other hand, probe B hybridizes with the gene of interest on the X chromosome and produces a red fluorescent color.

a. If a normal female individual is studied. How many chromosomes will light up green and how many will light up red? Explain your answer.
b. If the individual is a male, how many chromosomes do we expect to light up green and how many will light up red? explain your answer
c. If a female with Down syndrome is studied. How many chromosomes do we expect will light up green and how many will light up red? Explain your answer.
d. How many chromosomes do we expect to light up green and how many will light up red if we study an individual with Klienfelter syndrome? Explain your answer.
