What is in genetics, what is synthens?

Science on genetics that itself studies singular genes and, as they affect the body, defines synthans as the occurrence where two or more genes are placed in the same chromosome shared by different species. The science of genomic, which occupies the context of all genes and their mutual relations, then specifies the concept as shared genes that have a specific order. For example, if species A has genes 1, 2, 3, 4 and 5, while type B has genes 1, 2, 5, 3 and 4, both types have "syntenic genes" because of the genes 1 and 2 are arranged in the same order. The main point of the syntenna concept is the discovery of the genetic history and affinity of the species. When combined, the words are translated as "on the same tape". One of the first studies concerning gene syntenna was observation of bacteria with multiple chromosomes, such as the "rhodobacter sphaeroides" and "Burkholderia cepacia", in which some chromosomes contained the same genes. Studies concerning syntenic genes have spread when the genome sequence of drUhu fruit flies "Drosophila Melanogaster" in 2000 completely decoded. Soon thereafter, the genomic sequences were decoded with another 11 species of fruit flies, allowing genetics and genomists to compare MUM genomes.

Many scientists point to the theory of evolution as the cause of syntna. The assumption is that at the beginning the genome of a particular species is arranged in a certain way, but because the subsequent generations and different species are produced for thousands or millions of years, the genomic sequence is not somewhat satisfied. These small divergence are said to occur very slowly, with an About 200,000 years interval between each occurrence

For evolutionary theorists, synthens could be the result of a single and common origin, given that many animals share a large percentage of similar syntenic sequences. In fact, several studies have shown that about 90% of human and mice genomes are arranged PodoBně. However, other scientists argue that synthesus is not necessarily evidence of the theory of evolution and a single origin, but only illustrates that species are undergoing adaptation processes, instead of evolution. The concept also shows that all living creatures, including flora, are created with an "intelligent design" using similar materials that are assembled differently.
