Bipolar disorder has a strong and complex genetic component. perhaps one reason that the genetic component of bipolar disorder is so strong is that

It is passed on from one generation to another

Explanation:

The studies conducted till date on families having hierarchical occurrence of bipolar disorder represents that BP is caused because of linkages in the chromosomal regions. Since this disorder reoccur in the next generation, biologist believe that there are high chances that BP is associated with gene Some specific genes have also been found and suspected to be associated with BP and these are G72/DAOA, TPH2, DISC1,5-HTT, and NRG1.

it's     c       this is a cell (b) with a nucleus (c) containing dna (a). the dna is organized into chromosomes (d). a section of the chromosome that codes for a trait is called a gene (e).

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
