The plant Arabidopsis thaliana contains significantly more genes than either C. elegans or Drosophila. Which statement is true?

Question

Quizplus · Accepted Answer

Arabidopsis has a larger number of genes due to duplication events that have occurred throughout its evolutionary history. These duplication events can result in the conservation of duplicate genes, as well as divergence and specialization of gene function, leading to a greater diversity of proteins. While many Arabidopsis genes are also present in other plants, there are still many genes that are unique to Arabidopsis. Lastly, although there are now many plant genomes that have been sequenced, Arabidopsis was the first plant genome to be fully sequenced.
