Identify whether hybridization would likely lead to speciation or homogenization in each scenario. Several breeding pairs of cactus finch ground finch hybrids have successfully produced fertile, viable offspring for at least three consecutive generations. These hybrids have been unsuccessful breeding to non-hybrid cactus finches or ground finches. Are the hybrid finches likely to be speciating or homogenizing? The Texas bluebonnet, a flower native to Texas, grows wild along roadsides. It is also planted along roadsides in many beautification projects across Texas. Breeding between the planted blucbonnets and wild bluebonnets produces a hybrid that is genetically compatible with both parental varieties. Are the hyrbid blucbonnets likely to be speciating or homogenizing? Helianthus anomalus is a hybrid sunflower created by the natural breeding of H. annuus and H. petiolarus. Helianthus anomalus is a fertile, viable hybrid that can only successfully reproduce with other H. anaomalus. Are the hybrid sunflowers likely to be speciating or homogenizing?

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
