GO Term : GO:0009677 double fertilization forming two zygotes GO

Namespace:  biological_process Obsolete:  false
description  Rudimentary double fertilization where one of the two sperm nuclei from the pollen tube fuses with the egg nucleus to form a 2n zygote, and the other fuses with the ventral canal cell nucleus to form a second zygote, which soon degenerates. An example of this process is found in the Gnetophytes, such as Welwitschia mirabilis.

GO:0019953 sexual reproduction A reproduction process that creates a new organism by combining the genetic material of two organisms. It occurs both in eukaryotes and prokaryotes: in multicellular eukaryotic organisms, an individual is created anew; in prokaryotes, the initial cell has additional or transformed genetic material. In a process called genetic recombination, genetic material (DNA) originating from two different individuals (parents) join up so that homologous sequences are aligned with each other, and this is followed by exchange of genetic information. After the new recombinant chromosome is formed, it is passed on to progeny.
GO:0044699 single-organism process A biological process that involves only one organism.
GO:0008150 biological_process Any process specifically pertinent to the functioning of integrated living units: cells, tissues, organs, and organisms. A process is a collection of molecular events with a defined beginning and end.
GO:0000003 reproduction The production of new individuals that contain some portion of genetic material inherited from one or more parent organisms.
GO:0051704 multi-organism process A biological process which involves another organism of the same or different species.
GO:0022414 reproductive process A biological process that directly contributes to the process of producing new individuals by one or two organisms. The new individuals inherit some proportion of their genetic material from the parent or parents.
GO:0044702 single organism reproductive process A biological process that directly contributes to the process of producing new individuals, involving a single organism.
GO:0044703 multi-organism reproductive process A biological process that directly contributes to the process of producing new individuals, involving another organism.
GO:0009566 fertilization The union of gametes of opposite sexes during the process of sexual reproduction to form a zygote. It involves the fusion of the gametic nuclei (karyogamy) and cytoplasm (plasmogamy).
