Segmentation in biology is the division of some animal and plant body plans into a linear series of repetitive segments that may or may not be interconnected to each other. This article focuses on the segmentation of animal body plans, specifically using the examples of the taxa Arthropoda , Chordata , and Annelida .
Example of a biological network between genes and proteins that controls entry into S phase. However, with knowledge of network interactions and a set of parameters for the proteins and protein interactions (usually obtained through empirical research), it is often possible to construct a model of the network as a dynamical system .
Evolutionary developmental biology seeks to explain the origins of diverse body plans. Body plans have historically been considered to have evolved in a flash in the Ediacaran biota ; filling the Cambrian explosion with the results, and a more nuanced understanding of animal evolution suggests gradual development of body plans throughout the ...
Earthworms are a classic example of biological homonymous metamery – the property of repeating body segments with distinct regions. In biology, metamerism is the phenomenon of having a linear series of body segments fundamentally similar in structure, though not all such structures are entirely alike in any single life form because some of them perform special functions.

Trans-organismic communication is when organisms of different species interact. In biology the relationships formed between different species is known as symbiosis. These relationships come in two main forms - mutualistic and parasitic. Mutualistic relationships are when both species benefit from their interactions.
A segmentation gene is a gene involved in the early developmental stages of pattern formation. It regulates how cells are organized and defines repeated units in the embryo . Segmentation genes have been documented in three taxa: arthropods (i.e. insects and crabs ), [ 2 ] chordates (i.e. mammals and fish ), and annelids (i.e. leeches and ...
If you have an inherited intolerance to alcohol, a mutated gene could be the culprit. An at-home DNA test could detect whether you have the mutation, but doctors say there could be some drawbacks.
