What is the interaction of the gene?

Interakce genu je souhra mezi více geny, která má dopad na expresi fenotypu organismu. While the expression of physical properties is often described as a result of inheritance of two genes, one of each allele from each parent, it is actually much more complicated. Skupiny genů vzájemně interagují a vysvětlují, proč jsou fenotypy tak variabilní mezi jednotlivými členy druhu. Pochopení genových interakcí je důležitým aspektem porozumění dědičnosti, zejména dědičnosti škodlivých rysů. K tomu může dojít, když organismus zdědí například dva různé dominantní geny, což má za následek neúplnou dominanci. This is commonly seen in flowers, where two flowers breeding that pass through dominant genes can lead to flowering unusual colors caused by incomplete dominance. For example, if they are dominant red and white, the offspring could be pink -free striped colors as a result of gene interaction.

Někdy jsou genetické vlastnosti zcela potlačeny. Lidé s albinismem mohou nést geny pro vlastnosti, kterénejsou exprimovány v jejich fenotypech, protože albinismus působí tak, aby tyto geny vypnul. This can also be seen in samples of coloring in animals, such as turtle cats, where unusual hair color is the result of interactions of selective genes, with genes turned off in some places and turned on in others.

Flicter fly is well studied in genetics and much of understanding how gene interactions work, comes from working with a fruit fly in the laboratory environment. In organisms, such as humans, where genetic experimentation is considered unethical, genetics are forced to rely on data from the existing population to learn about dominant and recessive properties and see how groups of genetic properties of interacts can. The interaction of the gene is the result of inheritance of genes that somehow conflict, which makes it impossible for all expression as coded or dismay a file withdrawalthe emotionally connected genes that interact with each other to express the phenotype.

Sometimes the interaction of the gene limits the production of certain proteins, often quite early in the development of the fetus. In other cases, it may disrupt protein coding to result in a garbled expression of physical properties. Hybrids often show a number of interesting gene interaction results. In some cases, interactions are beneficial and may develop into their own genetic properties, while in others the interaction of the gene may cause disadvantage and eventually die out.
