Although the pumpkin is considered a diploid today, meaning that it has only two copies of each chromosome, the genome sequence analysis revealed that between 3 million to 20 million years ago, two different ancestral species combined their genomes to create an allotetraploid - a new species with four (tetra-) copies of each chromosome, from two different (allo-) species. (cornell.edu)
Typically after an allotetraploid is formed, the genome will experience downsizing and gene loss, eventually transforming the new species back into a diploid. (cornell.edu)
