Question

Out of cucurbita and papaya which one will show geitonogamy and why?

Answer 1

papaya is dieocious i.e male and female flowers occur in separate plants so that it prevents autogamy and genitongemy (method of self pollination)

Answer 2

In both cases of Cucurbits and Cucumber, geitonogamy will be prevented.

This is because in the case of Cucurbits and cucumber both the male and female reproductive parts are in different plants to prevent self-pollination.

As a result of which, geitonogamy will be prevented both in cucurbits and in cucumber.
