There is a universal fact that every individual plant species in this world will multiple into several new species or copies either through sexual or asexual reproduction. For this sexual reproduction to be taking place, pollination has a pivotal role in each & every flowering plants. The male gametophytes are present in the pollen grains & are produced in the anthers & the female gametophytes are present in the stigma on which the male gametophyte the pollen grains are attached & thus pollination takes places in flowering plants. Homozygosity of crop species can be increased by autogamy. Autogamy leads to heterosis but do not show inbreeding depression. Allogamy shows considerable amount of heterosis & show mild to severe inbreeding depression. They are highly heterozygous. Considering the tremendously increasing population, the world can’t be survived if there is no pollination in the flowering plants. This makes us to realize,” how much precious is the pollination is”.
