What percentage of someone’s genetic background may contribute to alcohol dependency?

The percentage of an individual genetic background that may contribute to alcohol dependency is 50%.

Explanation:

Alcohol dependency refers to a chronic disease in which the affected individual has an uncontrollable urge for alcoholic drinks. There are many factors that can cause one to depend on alcohol and one's genetic background is one of them.

Recently, researchers have been able to identify a specific gene that is responsible for development of alcoholic dependency. Before now, scientific studies have been able to proof that children born by alcoholic parents have high tendency of becoming alcoholic adults. The percentage of genetic heritage that is responsible for alcoholic use is as high as 50%

glaciers are melting causing sea levels to rise wgich could flood out land

explanation:

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
