Reproduction - "the birds and the bees"


Prunus cerasus is an allotetraploid species. Allotetraploids are created as a result of both chromosome sets of each parent being present in gametes.  Sour cherry flowers are hermaphroditic, having both male and female on same flower.  While they are hermaphroditic, they can still do cross-fertilization.  Normally, sour cherries are self-fertilizing and do not require a pollinator for fertilization, but bees can still be used.Image from antaldaniel at
