Final answer:
The claim that Mississippi's constitution defines a person from the moment of conception is false. The U.S. Constitution's Fourteenth Amendment defines citizenship and provides equal protection, which supersedes individual state constitutions.
Step-by-step explanation:
The statement in question is false. Mississippi's constitution does not define a person as every human being from the moment of conception based on a ballot initiative. Over time, individual states have created their own constitutions which have reflected their respective political and social climates. An example of such state-specific amendments includes the poll taxes and literacy tests that were historically included to disenfranchise certain groups, particularly African Americans, from voting. The Fourteenth Amendment of the United States Constitution, however, provides a broader definition of citizenship and guarantees equal protection under the law for all persons born or naturalized in the country. It's important to differentiate between state constitutions and the federal constitution when discussing legal definitions and rights.
