Final answer:
The Human Genome Project published data in 2012 that provided a map of 38 million SNPs that span all the human chromosomes.
Step-by-step explanation:
The project that published data in 2012 and provided a map of 38 million SNPs that span all the human chromosomes is the Human Genome Project.
The Human Genome Project was an international effort to sequence all 3 billion bases (DNA base pairs) of the human genome. It aimed to identify more than 20,000 human genes and completed a chromosome map locating where the genes are located on each chromosome.
The Human Genome Project was completed in 2003, but the analysis of the data continues to this day.
