Vedclass · Answer

(D) Outbreeding devices are mechanisms developed by flowering plants to discourage self-pollination and promote cross-pollination to increase genetic diversity.$1$. $Dichogamy$: In this process,the stamen and stigma mature at different times,preventing self-pollination.$2$. $Self-incompatibility$: This is a genetic mechanism that prevents pollen from the same flower or other flowers of the same plant from fertilizing the ovules.$3$. $Heterostyly$: This refers to the condition where flowers have different lengths of styles and stamens,which physically hinders self-pollination.Since all these methods are strategies to prevent self-pollination,the correct answer is $D$.
