Amphioxus Genome Reveals Recombination Secrets Hidden in Extreme Heterozygosity
Scientists have sequenced the amphioxus genome, a close living relative of vertebrates, and found unusually high heterozygosity — large genetic differences between chromosome pairs. The extreme variation allowed researchers to study recombination patterns and genome evolution in fine detail, offering clues about how genetic shuffling works and how it shaped the ancestors of all vertebrates, including humans.
Why now: The newly reported amphioxus genome sequence offers rare insights into recombination and vertebrate evolution, drawing attention from genetics researchers.
