- Why is one phase of a plant dominant (Alternation of generation)?

- What does dominant generation mean - Biology Stack Exchange
In my texbook it is written that for non- vascular seedless plants the dominant generation is the gametophyte as the gametophyte generation is larger and longer lived Is the criteria for dominant
