The true statements are:
- A single gene can influence multiple traits. (pleiotropy)
- A single trait can be controlled by multiple genes. (polygenic inheritance)
"A single gene can control a single trait" is sometimes true for simple Mendelian traits but is not generally true. "A single trait can alter multiple genes" is incorrect—traits are the result of genes and environment, not the other way around.
