Self-pollination

Vedclass · Answer

(D) Flowering plants have evolved several 'outbreeding devices' to discourage self-pollination and encourage cross-pollination. Self-pollination leads to inbreeding depression over successive generations,which reduces the genetic diversity and fitness of the plant population. Common outbreeding devices include: $1$. Dichogamy: Pollen release and stigma receptivity are not synchronized. $2$. Herkogamy: Anther and stigma are placed at different positions so that pollen cannot come in contact with the stigma of the same flower. $3$. Self-incompatibility: $A$ genetic mechanism that prevents self-pollen from fertilizing the ovules. $4$. Production of unisexual flowers. Therefore,the correct answer is $D$.
