Final answer:

Toll-like receptors (TLRs) are germ line encoded, indicating that their genetic information is inherited and represents a difference from T-cell receptors (TCRs) which utilize genetic recombination.

Step-by-step explanation:

TLRs, or Toll-like receptors, are indeed germ line encoded, which means the genes that produce these receptors are inherited and not subject to somatic recombination like T-cell receptors (TCRs). TLRs play a critical role in the immune system by recognizing pathogen-associated molecular patterns (PAMPs) and initiating an immune response. This is in contrast to TCRs, where a vast array of receptors is generated through a process of genetic recombination to recognize an immense variety of antigens.
