'alternation of generation' is a correct and usable phrase in written English.
It can be used to describe a type of life cycle in plants and animals where two (or more) distinct forms alternate between generations. For example, in frogs, the female lays eggs which develop into tadpoles, which later undergo metamorphosis into adults. This is an example of alternation of generation.
Plants undergo alternation of generation in which reproductive cells develop in the plant body ("sporophytic generation") and then differentiate into a multicellular gamete-forming "gametophytic generation".
This technique is based on the combination of the operator called uni-modal normal distribution crossover (UNDX) [ 12] with the alternation of generation model called minimal generation gap (MGG) model [ 13].
A critical role of moss 2 KNOTTED LIKE HOMEOBOX (KNOX2) transcription factors was demonstrated in preventing the development of gametophyte leafy shoots from diploid embryos before meiosis [ 9] indicating a critical role for the evolution of KNOX2 in establishing an alternation of generation in land plants.
All Lessonia species possess an alternation-of-generations life history, which is characterized by two alternating stages, a diploid macroscopic sporophyte stage (the stage of sample collection for this study) and a microscopic gametophyte haploid stage.
The life cycle of pteridophytes exhibits an alternation of generations between gametophytes and sporophytes.
Liverworts have an alternation of generations similar to that of mosses, and, as with mosses, the gametophyte generation is dominant.
This type of life history involves an alternation of generations, a phenomenon not occurring in haplobiontic (1n or 2n) life histories.
This multigenerational life cycle is called alternation of generations; it occurs in some protists and fungi as well as in plants.
The alternation of generations illustrates an important principle, namely that cell lineages arising from single parental cells containing the same genetic potentiality may pursue mutually exclusive developmental patterns.
The tracheophytes' development of large plant bodies was made possible by vascular parts that carry water and food inside those plants and by a dominant sporophyte stage (the nonsexual phase in the alternation of generations in the life cycle of certain plants and algae) with a microscopic-sized gametophyte (the sexual phase in the alternation of generations).
The bryophytes show an alternation of generations between the independent gametophyte generation, which produces the sex organs and sperm and eggs, and the dependent sporophyte generation, which produces the spores.
