Crossing over and independent assortment
Mechanisms such as gene flow, mutation, genetic drift, and natural selection are all considered mechanisms for genetic variation. Non-genetic mechanisms, such as Lamarckian inheritance or acquired characteristics, are not considered valid mechanisms for genetic variation in the traditional sense.
One mechanism that increases genetic diversity in a species is mutation, which introduces new genetic variations. Another mechanism is gene flow, which occurs when individuals from different populations interbreed, introducing new alleles into a population. Finally, genetic recombination during sexual reproduction can also increase genetic diversity by shuffling existing genetic material in different combinations.
Recombinants take up the plasmid but do not incorporate it into the DNA. Transformants take up the plasmid and integrate it into the DNA. Recombinants wouldn't express the new genes while Transformants will.

During crossing-over, the genetic material from homologous chromosomes is swapped. This leads to a recombination of the genes. Simple example: Originally - ABCD alleles on one and abcd on the other. After crossing over - ABCd and abcD This creates offspring with non-parental phenotypes (traits), which are known as recombinants.
Self-incompatibility is a genetic mechanism in plants that prevents self-fertilization and promotes outcrossing. It ensures genetic diversity by rejecting pollen from the same plant or plants with similar genetic composition. This mechanism helps to maintain the health and adaptability of plant populations.

DNA is critical to life as it carries genetic information that determines an organism's traits and functions. It serves as a blueprint for the production of proteins and other molecules essential for life processes. The ability of DNA to replicate ensures the continuity of genetic information from one generation to the next.
