Pronunciation: re-kom'bi-nant


  1. A cell or organism that has received genes from different parental strains.
  2. Pertaining to or denoting such organisms.
  3. In linkage analysis, the change of coupling phase at two loci during meiosis. If two syntenic, nonallelic genes are inherited from the same parent, they must be in coupling. An offspring that inherits only one of them is recombinant and indicates an odd number of cross-overs between the loci; an offspring that inherits neither or both are nonrecombinant and may indicate an even number of cross-overs or none.
