Question

UT EID: 38. If three out of four individuals have the disorder, what is the inheritance of Brugada syndrome A. dominant B. recessive C. incompletely dominant D. codominant 39-40. The trinucleotide repeat region of the Huntington disease (HD) locus in six individuals is amplified by PCR and analyzed by gel electrophoresis as shown; the numbers to the right indicate t sizes of the PCR products in bp. 5bp primers were designed just outside the repeat region. Normal alleles for HD gene contain up to 35 CAG repeats, while disease-causing alleles carry 36 or more. more the repeats, the earlier the age of disease onset 310 bp 160 bp 112 bp =|-|--|-100 bp 39. Which individuals are most likely to be affected by Huntington disease, dominant disease? knowing it is an autoson A. 1,2 B. 1, 2, 3 C. 1, 2, 3,5 40. In which of these individuals is the onset of disease likely to be earliest? A. 1 B. 2 C. 3 D. 4 E. 5
