Question

pollnation in pea plants can occur in tree ways true or false

Answer 1

Ambiguous — but usually considered False.

Briefly:
- In ordinary descriptions peas mainly show two natural modes: self-pollination (autogamy) and cross-pollination (xenogamy, usually insect-mediated).
- Some sources split cross-pollination into geitonogamy (transfer between flowers of the same plant) and xenogamy (between different plants), and then list three categories (autogamy, geitonogamy, xenogamy). Also one can add artificial/human-assisted pollination as another category.

So if the question means “are there exactly three distinct ways?” — it’s ambiguous; most textbooks count two natural ways, but you can list three if you subdivide cross-pollination.
