New Chromosome Numbers from Hybridization

GENES-CKWRGY

Some species of plants can hybridize where the resulting individuals have a new chromosome composition that is a blend of the parental chromosome sets. This concept is referred to as allopolyploidy.

Consider two plant species where Species A has 2n = 18 chromosomes, and Species B has 2n = 16 chromosomes.
