However, this analysis did not examine vertebrates, so could say nothing about later duplication events.

Rarely, a region of chromosome 21 will undergo a duplication event.

The evolution of mir-2 is characterized by successive expansions by duplication events.

In this model after a duplication event, both paralogs suffer deleterious mutations leading to functional degradation.

GypB can be found only in gorillas and some of the higher primates suggesting that the duplication events occurred only recently.

This duplication event occurred in an ancestor of the choanoflagellates and metazoans.

The two Osp proteins show a high degree of sequence similarity, indicating a recent duplication event.

This expansion in the angiosperms is thought to be due to at least one gene duplication event.

The MSA of the closest clade to humans all fell under the same duplication event.

The duplication event likely occurred sometime in the chordate lineage near the divergence of the Coelacanth.
