Answer 2

Answer:

Explanation:

Hi✌️✌️

Outbreeding devices are mechanisms which are followed and adapted by the plants in order to prevent self pollination. The examples of outbreeding devices are:

Unisexuality: The plant may be unisexual, which means it may exhibit either male or female gametes.

Dichogamy: In this mechanism the male reproductive part the anther and the female reproductive part the stigma matures at different times, therefore avoids self pollination.

Self sterility: The gene in the female reproductive part of the flower which recognizes the gene present in the pollen grain of the same plant, prevents the fertilization results in self sterility.

Herkogamy: The natural barriers prevents the the pollen of the same flower to pollinate the ovary of the same flower.

Hetrostyly: The anther and stigma are present at different levels of the flower which prevents the self pollination and fertilization.

Pollen prepotency: The pollen of the different flower germinate faster than the pollen of the same flower thus preventing self pollination.

I hope it will help you you ❣️❣️
