Final answer:
A positive result of a genetic test belongs to the immediate family because they share genetic material and are at risk of inheriting the same disorder. The decision to share genetic test results with extended family should be based on factors such as the potential impact on their health and the individual's own preferences.
Step-by-step explanation:
According to most bioethicists, a positive result of a genetic test belongs to the immediate family because they share genetic material and are at risk of inheriting the same disorder. Sharing this information with immediate family members allows them to make informed decisions about their own health and the potential risks to their offspring.
For example, if a genetic test reveals that a person carries a gene for a recessive disorder, their siblings might also be carriers, and their children might be at risk of inheriting the disorder.
With regards to extended family, the stand of most bioethicists is that it depends on the specific circumstance. While immediate family members have a closer biological relationship, bioethicists recognize the importance of considering the well-being and privacy of individuals.
The decision to share genetic test results with extended family should be based on factors such as the potential impact on their health and the individual's own preferences.
