Flowers are the reproductive, seed-producing structures of angiosperms. Typically, flowers consist of sepals, petals, stamens, and carpels. Sepals and petals are the vegetative flower organs. Stamens and carpels are the reproductive organs.
Flowers must be pollinated to produce seeds. In angiosperms, pollination is the transfer of pollen from the anther of the stamen (the male structure) to the stigma of the carpel (the female structure). Flowers may be self-pollinated or...

When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.
Positive Frequency-Dependent Selection
In positive...
