Q.) A geneticist is mapping the location of three markers relative to a disease causing genetic variant. Her results are shown below. Based on the results of the mapping, answer the following questions.
Marker
Recombination fraction relative to disease gene
X
0.3
Y
0.5
Z
0.1
a.) Which marker is closest to the disease-causing genetic variant? Support your answer. (2)
b.) Which marker is not linked to the disease-causing variant? Support your answer. (2)
c.) If the geneticist scored 200 chromosomes for recombination, how many recombinants did she observe for each marker? (2)
