Final answer:
The HD gene was likely further localized during or shortly after the Human Genome Project period from 1990 to 2003, based on the general timeline of the genome mapping efforts; however, specific details are not provided in the references shared.
Step-by-step explanation:
The question asks when the HD gene was further localized and where it was localized. While the provided references do not directly mention the 'HD gene' or the specifics of its localization, the timeline of the Human Genome Project (HGP) gives a broader context for understanding the progress in gene mapping and localization during the HGP era. Considering that the announcement in 2001 indicated the mapping of the human genome was complete, and Celera also contributed to the effort around the same time, it is likely that further localization of genes, including the HD gene, would have taken place during or shortly after the HGP period, which officially ran from 1990 to 2003. The specific localization of the HD gene, however, is not detailed in the provided references and would require further information to answer accurately.
