Teacher:Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.
Teacher: Now, understand the problem? Solve this instance: Question: Is age at natural menopause linked with the follicle-stimulating hormone receptor region : a sib-pair study?
Answer: Possibly, age at natural menopause in the more or less normal range is not part of the spectrum of phenotypes determined by mutations in the FSH-receptor gene. Alternatively, our results might be explained by genetic heterogeneity in the left tail of the distribution of menopausal age. This can limit the chance of finding a genetic locus, especially if this factor has a modest contribution to the phenotype.
