  1. Suicide is a consequence of depression. There is a pronounced genetic predisposition to depression and associated mental disorders. Twin studies have shown that 40% of the variability in the population's risk of depression is genetically determined. Further, large statistical studies were conducted, where the genome of tens of thousands of people with and without depression was compared. As a result, we found variants in the DNA that are noticeably more common in people with depression, mainly in the genes responsible for the production, transmission and susceptibility of serotonin and dopamine receptors. But there are other variants in the DNA associated with depression, but they are located in areas of the genome where there are no genes, and they seem to play a regulatory role.

  2. The tendency to have a major depressive episode is inherited. Most often, it is he who pushes people to commit suicide. So, we can say yes, the tendency to commit suicide can be inherited in some way

  3. Unfortunately, there is no knowledge in genetics. But just in a human way: if you raise a child in love, understanding, attention and support, help him cope with moral difficulties, then he will not even have thoughts of suicide! A lot depends on the upbringing and the atmosphere in which a person grows up.

  4. I can't prove my answer scientifically, but I can give you a real-life example…
    The woman committed suicide, the reason seems to have been a prolonged depression. She left two sons (they were about 3-4 years old at that time). The boys lived with their grandmother after their death, grew up together, but one was active, and the other was so pessimistic, there was no question of resistance to stress. It all ended with the fact that he became depressed and at the age of 15 he had his first suicide attempt (well, okay, who is not young, stupidly), but then another six… the seventh was successful.
    In general, after this situation, I can draw a conclusion. First of all, of course, our ancestors bring in us their predispositions to something, but not in 100% volume. Secondly, one way or another, everything still depends on us, we build our own perception, decide for ourselves who we should be, a person running away from problems or a person who is able to deal with difficulties and learn from them.

  5. Perhaps I will express a non-trivial thought about this and not quite to the point.

    In nature, there is a mechanism of “programmed” death: fish after spawning; plants after abundant flowering; some species of animals that die not from old age, but from other causes; bacteria that do not” age”, but divide all the time, but under unforeseen conditions emit a toxin that destroys them. One of the meanings of this mechanism is probably not to pass on “genetic errors” that are dangerous for the species to the offspring, but obviously not only that. In this regard, the tendency of people to suicide can be considered as the same natural mechanism of “programmed” death, triggered by nature and which we, thanks to the psyche and everything connected with it, sublimate and pass off as “mental torment” leading us to suicide.
