Sentences with phrase «gene duplication event»

Not exact matches

Rather than supporting a genome duplication event at the time when yeast evolved to have twice the number of chromosomes, their data indicated that the duplicated genes had begun to diverge long before.

Unexpectedly, they show that the appearance of duplicated genes was not caused by a simple duplication of the whole genome but rather by a mating («hybridization») event between two different species.

The other two genes appeared to be paralogs — genes that are the result of a duplication event in the DNA.

«In order for something to evolve, duplication of a gene is the most important event,» Hsu says.

Both of the new studies found that copy number events involving either duplication or deletion of the 25 to 30 chromosome - 16 genes — several of which are known to play a role in the developing brain — appear to cause autism.

Although none of the German Neolithic samples carries the copy number expansion of the AMY2B gene associated with starch digestion, we find that this gene is present in three copies in NGD, though this is due to a large segmental duplication that is shared with multiple modern dogs, an event separate from the tandem AMY2B duplications.

Altogether, the data presented in this study reinforces the evolutionary importance of the two rounds of whole genome duplication that occurred in the vertebrate ancestor and sheds light on the differential behaviour of gene duplicates that arose in these events.
