Genome Sequencing vs Genetic Mapping

There was a recent paper in Science about the mapping of theĀ Artemisia annua genome. I’ve seen several people interpret this as another genome sequence. It’s hard to blame anyone for this confusion given headlines like “Scientists map the maize genome!” to describe the sequencing of the maize genome. So what’s the difference between a sequenced genome and a mapped genome? I’m glad you asked!
