Do they have sex (X and Y) chromosomes?
What is the chromosome number of Ginkgoes?
The 2n chromosome number of Ginkgo biloba is 24.
Ginkgo biloba, known as the Maidenhair Tree, is a unique tree with no close living relatives.Ginkgo is a dioecious gymnosperm, male and female are separate trees.The sex chromosomes (XX females and XY males, just like humans) are difficult to distinguish, so the tree%26#039;s gender is not easily classified.The pollen and ovules grow on the short spurts, very seldom on the leaves (Ohatsuki). Occasionally both genders are found on the same tree.It is possible to distinguish the sexes by chromosome morphology, because the female lacks one tiny satellite on one chromosome.
