Cross-breeding: Outbreeding, or the breeding of unrelated individuals.
Dipterocarp: Trees of the family Dipterocarpaceae: resinous trees that are found in the old world tropics.
Gestation: The state of being pregnant; the period from conception to birth.
Inbreeding: The breeding of closely related individuals. An inbred population usually has less genetic variability and this is generally disadvantageous for its long-term survival and success.
Indigenous: Native, or a species that occurs naturally in an area.
Subspecies: A population usually restricted to a geographical area that differs from other populations of the same species, but not to the extent of being classified as a separate species.
