Explanation:

because the pollination is within the same flower (as the flower donot open). because of which there is no chance of cross pollination and hence no genetic diversity ..

hope it helps ..

Disadvantage of cleistogamy is :

1. The offspring produced have limited genetic diversity.

Since cleistogamous flowers don't open at all and anther and stigma lies close to each other. Hence these flowers are invariably autogamous and favours self pollination. So ultimately there will be less chance of any variation to occur.
