The hereditary traits are passed from parents to offspring through the genes found in the nucleus of the reproductive cells. In this core are a threadlike bodies called chromosomes, each made up of thousands of genes, are composed of deoxyribonucleic acid (DNA) that’s who transfers the estate.

Each reproductive cell carries a prize of 46 chromosomes and myelosis (a special type of cell division) causes the number of chromosomes is halved, ie 23. When the egg is fertilized by sperm obtained the 46 chromosomes, 23 from each parent. At this time the biological heritage of the new being is determined.

For each particular feature is a pair of genes, one from the mother and one father. But genes are dominant (greatest influence) and recessive (less influence), so the characteristics appear with the information marked by dominant genes. The combinations of dominant and recessive genes can be multiple, and the results.

The brothers do not share exactly the same inheritance, with the exception of identical twins. Each child inherits half the chromosomes of the father and mother and this half is a random selection, so what the results will be different combinations. According to statistics, in theory, a couple could give 64 million children genetically different.

We should be aware but not overreacting. Tourists generally do not like visiting poultry farms, so the real risk for tourists is very low. There is no reason not to travel only for fear of the AI. Centers for Disease Control and Prevention (CDC) does not recommend travel restrictions to countries that have been infected with H5N1 and do not recommend the use of personal protective equipment such as respirators, gloves, or surgical masks as protection against the AI, unless the health officer. Gloves should be worn by people who clean the objects that are potentially contaminated.

An entry screening (selection entrants) at the entrance to a country were discussed. They take into account the incubation period of Avian Influence, while flights between the countries of origin to destination countries and an analysis of the progression of symptoms from asimpto-automatic to appear, so hopefully people who may be infected from infected countries could be prevented plague into the country that have not been exposed to plague. However, this method is considered ineffective, because the influenza incubation period longer than the flight time between countries, so that infected patients are not detected at screening.

In addition, if found infected people on the flight was not possible that there are other people who are infected but without symptoms, so that ideally all passengers must be quarantined.
