Significance of several BUSCO target IDs for the same gene

Question

[CoLa]

After assesing the gff files of the single-copied BUSCO Outcome, I noticed, that Target_IDs are used several times, just adjusted with _ and a number. Mode was set to genome.

For example: 10087at7088_4 and 10087at7088_8 are represented in the same gff, but are found on different contigs. Does this mean parts of the gene is represented on different contigs? Or does this mean the gene is duplicated? AFAIK duplicated and truncated BUSCOs are stored seperately.

What is the significace of i. I looked up the GFF3 documentations (https://github.com/The-Sequence-Ontology/Specifications/blob/master/gff3.md) and could not find anything.
