Pronunciation: mer'o-zi'got

Definition: In microbial genetics, an organism that, in addition to its own original genome (endogenote), contains a fragment (exogenote) of a genome from another organism; the relatively small size of the exogenote permits a diploid condition for only a limited region of the endogenote.

[mero- + zygotos, yoked]
