According to research on gender dysphoria, a biological predisposition contributes approximately 60 percent to the cause. environment and genetics contribute equally to the cause. a biological predisposition contributes approximately 60 percent to the cause. it cannot be determined, as yet, regarding the extent of the genetic and environmental contributions to the cause. there is a specific set of genes that seem to contribute most to the cause.

Explanation:

Gender dysphoria is a state/distress of an individual due to its gender identity. This disorder appears when a person feels like their  gender assigned at birth is not matching with their real gender identity. This is a psychological state and these persons very often are transgender.

Twin study has shown that genetics has influence on this condition: it is 62% heritable. However, the real cause is still not confirmed, because of disagreements among scientists.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
