Pattern formation is the developmental process by which cells acquire different identities, depending on their relative spatial positions within the embryo.
Pattern formation ensures that tissues and organs develop in the correct place and orientation within the body..
For development, it is the biophysical laws by which these structures deform, move, and restructure that are essential for morphogenetic rearrangements at developmental length- and time-scales.Oct 6, 2011.
For instance, the segmentation process along the longitudinal axes of vertebrates and invertebrates [2, 3], the fine-grained mixtures of different cell types appearing in both plant and animal tissues [4], the regular arrangement of organs along the plant shoot [5], and the cell polarity patterns appearing in multiple .
Examples of pattern formation:
Drosophilla developmental biology (gene action of Bicoid and Nanos).
Bicod is the maternal effect gene that helps to determine the patterning of anterior parts of an organism, while Nanos affects the parental genes which aid in the formation of a posterior abdominal segment. 2..
In developmental biology, pattern formation describes the mechanism by which initially equivalent cells in a developing tissue in an embryo assume complex forms and functions.
Embryogenesis, such as of the fruit fly Drosophila, involves coordinated control of cell fates..
Possible mechanisms of pattern formation in biological systems include the classical reaction–diffusion model proposed by Alan Turing and the more recently found elastic instability mechanism which is thought to be responsible for the fold patterns on the cerebral cortex of higher animals, among other things..
Pattern formation is genetically controlled, and often involves each cell in a field sensing and responding to its position along a morphogen gradient, followed by short distance cell-to-cell communication through cell signaling pathways to refine the initial pattern..
Pattern formation arises from the coordination and interplay of several mechanisms and processes across molecular, cellular and tissue scales.
At the cellular level, growth, cell fate specification, migration and cell–cell interactions can be important and influence each other during the formation of a tissue..

All these classical and novel biophysical techniques are currently allowing researchers to access the ins and outs of genetic processes, which now can be understood quantitatively through statistical mechanics, thermodynamics and chemical kinetics.
Biological rules and laws are often developed as succinct, broadly applicable ways to explain complex phenomena or salient observations about the ecology and biogeographical distributions of plant and animal species around the world, though they have been proposed for or extended to all types of organisms.
Therefore, the physical laws are an expression of the intelligence which determines the fulfilment of that purpose, i.e., the health, vitality, and harmonious functioning of the physical body.
Proper foods, relaxation, exercise, deep breathing, cleanliness, etc., are covered under the physical laws.
In summary, Biophysics looks for principles that describe patterns.
If the principles are powerful, they make detailed predictions that can be tested.
Therefore, the interdisciplinary research field of Biophysics will provide an increasingly amount of knowledge to fully understand the complexity of Genetics.
