  • (20) A test mating between two Manchester Terriers affected by Perthes' disease (PD) resulted in the birth of three affected males and two unaffected females.

Selection


Definition:

  • (n.) The act of selecting, or the state of being selected; choice, by preference.
  • (n.) That which is selected; a collection of things chosen; as, a choice selection of books.

Example Sentences:
