Genetics

(of an alga or other lower plant) having a life cycle in which the main form, except for the gametes, is diploid.
〔遗传〕二倍体的。比较HAPLONTIC 和DIPLOHAPLONTIC
Compare with haplontic and diplohaplontic
Example sentencesExamples
- Most brown algae undergo an alternation of generations life cycle, as does Ulva, but species such as Fucus reproduce via a diplontic life cycle, meaning the adult is the sporophyte and diploid.
- The chromosome changes seen in meristems 2-3 cell cycles after treatment provide a basis for diplontic selection; for the establishment of a new meristem from, perhaps, a few initial cells.
- Members of the order Fucales have a true diplontic life history.
- Unfortunately, current knowledge on architecture and programming of shoot meristem was not used in this explanation to support genetic results against diplontic selection.
- The diplontic life cycle is not seen in algae or plants.

diplont

noun

Genetics

In most diplonts, mitosis occurs only in the diploid phase, i.e. gametes usually form quickly and fuse to produce diploid zygotes.
Example sentencesExamples
- Therefore, with no further diplont or haplont selection, a certain number of seeds homozygous for the mutation will be formed in the inflorescence (1: 3 ratio, theoretically), and the mutant variation may be observed in all M2-families (the progeny of the same M1-plant).
- When as in Entamoeba histolytica and Giardia lamblia no sexual cycle exists, whether they are diplonts or haplonts is obviously irrelevant.

Origin

1920s: from diplo- 'double' + Greek on, ont- 'being' (from einai 'be, exist') + -ic.
