The potential for animal suffering.
-
The impact on biodiversity.
-
The safety of cloned meat for human consumption.
-
All of the above.
D
Correct answer
Explanation
The prospect of cloning animals for food production raises ethical concerns related to the potential for animal suffering, the impact on biodiversity, and the safety of cloned meat for human consumption.
What is the primary concern regarding the potential use of cloning for reproductive purposes?
-
The risk of genetic defects and health problems.
-
The psychological impact on cloned individuals.
-
The potential for creating designer babies.
-
The violation of natural reproductive processes.
C
Correct answer
Explanation
The primary concern regarding the potential use of cloning for reproductive purposes is the potential for creating designer babies, where parents could select specific traits or characteristics for their children, raising ethical questions about eugenics and social inequality.

-
The violation of natural evolutionary processes.
-
The potential for creating new diseases.
-
All of the above.
D
Correct answer
Explanation
The potential use of cloning to create genetically modified animals raises ethical concerns related to the potential for unintended consequences on ecosystems, the violation of natural evolutionary processes, and the potential for creating new diseases.
What is the primary ethical concern regarding the potential use of cloning to create chimeras?
-
