Such as a partial tetraploid salmon.

well polyploidy is where chromosones are unequally shared during cell devision, meaning duplicates of the same chromosome in one cell.
This can happen up to 4 times (tetraploid - 4 cells in miosis in which all 4 of that chromosome is placed in one cell)
the 'partial' part comes from how many chromosomes are wrongly places
- In full polyploidy all chromosomes return to the same cell (in mitosis this would leave the cell diploid)
- In partial only some of the chromosomes are correctly moved, leaving a duplicate of one or more chromosomes while still having some chromosomes in the right quantity
