Question

91. Which of the following is a disadvantage of
cleistogamy?
(1) The offsprings produced have limited genetic
diversity
(2) It needs to produce a lot of pollen grains
(3) There is a little probability of flower to get
pollinated
(4) There is always a need of pollinator​

Answer 1

Answer:

option 1 .

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 ..

plzz do follow and mark as brainliest..

Answer 2

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.
