Pattern challenges ectopic recombination model in primates
The developed algorithm detected ancient subgenome-specific repeats in the subterminal heterochromatin of Xenopus laevis, challenging the primate model of ectopic recombination.
- Field
- genetics and genomes
- What they did
- Scientists developed a k-mer based algorithm to identify specific genomic regions rich in repetitive sequences in different tetrapod species. Applying the method to the Xenopus laevis genome revealed the presence of ancient repetitive elements that originated in its distinct progenitors.
- Why it matters
- This allows testing the hypothesis that tetrapods inherit repetitive sequences differently than primates and understanding the evolution of their genome.
