Quizplus · Accepted Answer

Janelle inherited one normal allele from her father and one allele for MFX disorder from her mother. However, since she does not suffer from any variant of MFX disorder, this means that the disorder must be recessive in nature. Therefore, option D is the correct answer. We cannot conclude anything about whether Janelle's mother has MFX disorder or whether the disorder is sex-linked based on the information given.
