An individual race's vigor and vitality are diminished by continuous selfpollination. In order to prevent self-pollination and to promote cross-pollination,flowering plants have developed many devices. Cross-pollination is most frequently ensured by dichogamy and self-sterility. Dichogamy: Different maturation times for the anthers and stigmas prevent selfpollination. Self-sterility (or self-incompatibility): pollen grains from some flowers do not germinate on their stigma due to the presence of self-sterility genes. Examples include tobacco and potatoes.Answered by Pragya Singh | 1 year ago
