emergence of new kinds of living beings is only possible if the existing share with the "newcomers" their genes.That is, the set of amino acids, which are stored in the chromosomes of every living cell.All the genes of all mankind up an information bank.It turns out that the gene pool - a collection of data that characterize all human beings of the past, present and future.
Where is this information
themselves are chromosomes in the nucleus of cells.Each variety has its own unique set of in charge of its functions.Chromosomes are managed by processes that occur in a small single cell and throughout the body.Better compare them with a computer, as all the actions which will occur in the cell, they are already registered as a computer program.When dividing into two valuable set of duplicated and took each of the new cells.It turns out that every living organism receives information about all the creatures of their own species stored in genes.
human gene pool - a whole set of genes
The planet is home to several billion people.Absolutely each boasts its own set of genes.This information is individual and unique.The totality of the data, which are included in the chromosomes of people, and the gene pool of humanity.It is divided into groups based on ethnicity.For example, the gene pool of the Russian nation - is the aggregate information set of chromosomes of people of this ethnic group.
What is the importance of the concept
gene pool - it is possible to transmit ethnicity signs of future generations.When the population size is reduced, the conditions for its complete destruction.That is, there is a certain "critical mass" of the gene pool.If people no longer give birth to their own kind, the ethnic group may disappear from the face of the Earth.This applies to all mankind.Only the constant reproduction contributes to the continued existence of the form as such.Offset genes during fertilization is responsible for the emergence of new mutations.To play is continuous, the carrier of genetic information should be sufficient, and they are required to have genes that allow creatures reproduce.It turns out that the gene pool - that is, information about the health and cleanliness of the ethnic group, or humanity in general.
essence of the information contained in the chromosomes
genes are responsible in general for the whole body and not only.Color of eyes or hair, complexion and body shape due to hereditary information, ie the set of chromosomes that the child receives from his parents.In addition, he still gets the probability of acquisition of a disease.Now there is debate over the succession of temperament.But the human body is not perfect, and often faltering.Reproductive function is also affected.Due to departures child can get a damaged set of chromosomes, which will cause disease or mutation.This set will give it to his descendants, and this is a threat to the entire gene pool.Of course, one does not fail to destroy mankind.But if these violations are widespread, that threaten the existence of the species, as the inheritance of continuous chain.Science tries to find ways to combat the disease gene, but as long as it remains at the level of fantasy, so the preservation of a viable gene pool of humanity - one of the main tasks.
