Genome-Wide Association Study of Alcohol Dependence Implicates a Region on Chromosome 11
Is there a gene that causes alcoholism?

What part of the brain is responsible for addiction?
Addictions center around alterations in the brain’s mesolimbic dopamine pathway, also known as the reward circuit, which begins in the ventral tegmental area (VTA) above the brain stem. Cell bodies of dopamine neurons arise in the VTA, and their axons extend to the nucleus accumbens.

What genes are inherited from mother only?
Our mitochondrial DNA accounts for a small portion of our total DNA. It contains just 37 of the 20,000 to 25,000 protein-coding genes in our body. But it is notably distinct from DNA in the nucleus. Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.
What are the 3 types of genotypes?
There are three available genotypes, PP (homozygous dominant ), Pp (heterozygous), and pp (homozygous recessive).
