Question

what controls traits and inheritance?
gametes
nucleic acids
proteins
temperature

Explanation:

Nucleic acids (such as DNA) carry the genetic information that determines traits and is passed on during inheritance. Gametes are reproductive cells that carry nucleic acids but do not directly control traits. Proteins are the products of gene expression (based on nucleic acid instructions) but are not the controllers of traits and inheritance. Temperature can influence some biological processes but is not the fundamental controller of traits and inheritance.

Answer:

nucleic acids
