Genetic testing is performed on couple with son with CF. Results of genotyping to detect alleles at 5 polymorphic loci linked to the CRTR are shown. Risk of recombination between each of the loci and CFTR is known to be lass than 1%/
genetic markers father mother son with CF fetus
I 1,2 2,2 1,2 1,2
II 4,4 4,4 4,4 4,4
III 3,9 3.3 3,8 3,3
IV 1,1 1,8 1,8 1,1
V 4,8 5,5 5,8 5,8
Which of the following best represent the alleles present on the father's chromosem that has CFTR mutation?
a) I2 II4 III9 IV1 V4
b) I1 II4 III9 IV 1 V4
c) I1 II4 III3 IV 1 V8
d) I2 II4 III3 IV1 V4
e) I2 II4 III9 IV1 V8
Please any idea? Thanks!
