02:16Genetics of Speciation
19.0K
Speciation is the evolutionary process resulting in the formation of new, distinct species—groups of reproductively isolated populations.

02:40Pollination and Flower Structure
63.4K
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.

01:21Frequency-dependent Selection
21.8K
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.

01:31Formation of Species
39.0K
Speciation describes the formation of one or more new species from one or sometimes multiple original species. The resulting species are discrete from the parent species, and barriers to reproduction will typically exist. There are two primary mechanisms, speciation with and without geographic isolation—allopatric and sympatric speciation, respectively.

02:39Gene Flow
34.8K
Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.
