Can personality traits be passed through DNA? IF so, how have we proven it?

Answer 1

Maybe, we don’t know for sure
We are only just learning about the human genome. The project that identified them was just recently completed, but we haven’t found out what all the genes do yet.

So the question of nature over nurture is still undecided.
Did I like science fiction because my father did or do I like it because he was a rocket engineer and I was interested in what he did for a living? I did I develop an interest because I was an avid reader who was curious about science?

Eye color, hair color, height and a lot of other things are inherited characteristics determined by our genes; but those genes do have a random factor because some genes are recessive, some skip generations some are shared and some come from one parent or the other parent.

We know that some of the genes are junk and some of our genes are old data. For example when a fetus develops it has gills at one point; as the baby grows it passes through a portion of our genetic development (evolution).

You might like spicy food because your parents did or because in your culture it is common and you grew up with it. We don’t know for sure which way it works. We surmise that the physical parts of us are genetically determined, but we are not even sure exactly how that works.

The leader of the human genome project is currently working on diabetes. He has found a gene that has something to do with it. Is the disorder a genetic one, or do certain people have a genetic predisposition to get diabetes, or is it simply because your family likes sweets too much? He is working on the problem and is trying to find a cure. We know that there are several forms of diabetes; the basic condition is when the liver gets tired of making insulin and it can no longer control the sugar levels. Our bodies burn sugar for fuel and we take some of our food and convert it to sugar. When the human body is over exposed to sugar for some reason the production of insulin can get reduced or even stop. We don’t know the exact reason for this happening and why it seems to happen in some families more than others. The truth is probably because of a genetic predisposition and some other factors. We can say the same thing about a lot of other traits.

We don’t even know how a memory is constructed. It is more than just an electrical signal like a computer. The neurotransmitters, chemicals in our brains, are also involved. There is a lot we don’t know about or bodies and we are only just learning.

We are still unraveling the mystery of DNA and we are finding that it is a very efficient information storage system. It not only has all the information to create our bodies, but it includes a whole lot more on the specifics, with alternate versions, and pieces of old copies. Then exactly how do the chromosomes first meet and read the DNA? We know that when an egg is fertilized the roulette game starts. Around, and around the wheel spins and what comes up could be brown eyes, blue, or even green. It depends what was on the wheel and where it landed. We are just beginning to be able to predict where that ‘wheel’ will land and how to modify it. It is an exciting time with new frontiers being explored. We also have a lot of genetic issues to handle; moral issues like human cloning and stem cell research. We haven’t even decided what we are going to do when we find out how to control the DNA. If you want a baby with green eyes, it can be done, if you want one with blue eyes that can be done as well, and if you want one with eyes that can see into the infrared spectrum that could be possible one day.

Now imagine the tools of genetics in the hands of a group like the Nazis; they would create a race of super men and try to take over the world. They would remove the genes for all but whites and tamper in other ways. Just how much of that are we going to allow?

In the series Star Trek they had an eugenics war where a breeding program that used DNA manipulation created a race of supermen. They had a war and almost destroyed the planet in the process. In that world genetic engineering is heavily controlled and regulated; but not before they had a huge problem with it. Are we going down that route or will we handle it better? That is up to people like you to figure out.

Answer 2

Mood swings happen often and suddenly, half of which (depression and sadness) i tend to be secretive about. My mind is never on what it should be and I daydream a lot. I honestly have no clue what I'm saying since I like to talk and I'm daydreaming at the same time, chances are I wasn't thinking at all, just saying random stuff. Cant sit still. Come off as a ***** because I think I'm right. Seem arrogant and domineering. Like to argue and will win depending who against. Even if I lose I still will think I'm right. I tend to buy into everyones sob stories so I can get walked on easiely. Overemotional and sensitive to what others say, can't always handle critism esp. if under stress. Feet and legs always hurt. I'm always running late and forget everything. Overly love sleep. Have had alcohol and drug problems in the past, both of which were used to fill emotional voids. I want to get a long with people but I dont at the same time. I hate talking but love it at the same time. Most things I have a love hate relationship with. I like meeting new people and traveling.

Answer 3

PERSONALITY traits can't be passed trough DNA. It is only the physical and physiological traits that can be passed. If you have the same personality as your mother, that's because you lived in the same environment or because of an other environmental cause.
There has been absolutely no proof that a personality trait can be passed trough adn in Human species.

They are some traits of our personality that are passed to the next generation. And its not a theory, but a fact! This have even been proved by the observing birds and their youngs... Its mainly in the instinctive area that those traits are seen.
And such heritage is much more profound than scientists would like to agree with, as it underlying all the education process. In any cases such heritage could affect any aspects of a person behavior, from how it walks, to facial expressions.

If you want a proof, thenh, just try to observed more attentionally your childs if you have... Mine is in China, and his only 2years and 4 months, and she almost never saw me... She still prefer to eat bread than eating rice, like other chinese of her age.... Actually, she doesn't like rice at all!! I cannot talk about other traits, but this one is evident!!

Answer 6

yes, hormones control many of our personality traits, testosterone makes men aggressive depending on its levels and the levels of testosterone in fathers and sons is very similar. other chemicals such as endorphins are ur happy hormones, again they help control mood and personailty.our levels of hormones are controlled by our parents genes combined.
ur looks come from mixtures of hormones and this is well known
what is less well known is that moods and personalities are also controlled by hormones int eh exact same way.
ever notices that as a person gets older, both the way the look and the way they act(personailty) changes along with it.
