Hi, here a question from a non-native: I see often in scientific articles sentences such as:

Animals have approximately 20000 genes encoding proteins.

That sound a little bit odd to me. Would it be more correct to use the restrictive clause?

Animals have approximately 20000 genes that encode proteins.

Hello, jack001, and welcome to the Grammar Exchange.

Both sentences:

  • Animals have approximately 20,000 genes encoding proteins.
  • Animals have approximately 20,000 genes that encode proteins.

contain a clause with restrictive meaning (a reduced relative and a full relative, respectively) and are totally equivalent.
