Polyploidy 

Some organisms possess more than two sets of chromosomes—they are polyploid.  Allopolyploidy Condition in which the sets of chromosomes of a polyploid individual are derived from two or more species.  Autopolyploidy Condition in which all the sets of chromosomes of a polyploid individual are derived from a single species.

The frequency of recombinant gametes is half the frequency of crossing over, and the maximum frequency of recombinant gametes is 50%.  Recombinant gamete = Half of the frequency of crossing over

50% = 100%
