As we continue to unravel the genomes of more and more organisms, the contributions from this dynamic and ancient gene pool should become apparent. (scientificamerican.com)
In contrast, disorders that occurred equally among purebred and mixed - breed dogs appeared to represent ancient gene mutations that had become widely spread throughout the dog population. (cabi.org)
By comparing the V. carteri germ and somatic cell transcriptomes, Matt and Umen found that the somatic cells had more transcripts from young, lineage - specific genes, whereas the germ cells had more transcripts from ancient genes that are similar to those expressed in stem cells from animals and land plants.
