- Nbme Form 18 Answers
NBME Answers and Explanations! This child likely has a meningomyelocele (neural tube defect caused by failure of the neuropores to fuse in week 4, FA2020 p491). I recently took NBME 17 2 weeks out of my step one. 211 with 80% correct answers. There's 3 alleles present - 1, 2, and 3. The question asks what the child of a 1,3 x 2,2 pairing would be. Thus, it'd have to be either 1,2, or 2,3 because they have to inherit one of the #2 alleles from momma. From there, we see that all males with the 1,3 genotype are affected - don't get distracted by the 1,3 female! Since the question is asking for an unaffected male, the answer can't be 1.
