Question

what controls traits and inheritance?
gametes
nucleic acids
proteins
temperature

Explanation:

Nucleic acids, specifically DNA, carry genetic information that controls traits and inheritance. DNA sequences are passed from parents to offspring during reproduction. Gametes are cells involved in reproduction but don't directly control traits. Proteins are products of gene - expression but not the controllers of inheritance. Temperature can affect some traits but is not the main controller of inheritance.

Answer:

B. nucleic acids
