General depression can be an inherited trait, and it also can be caused by environmental or health factors.

Its hereditary/genetic thing. Not sure y they are but, there are some. Nothing wrong with it at all.

No.  The gene is carried on the X chromosome.  But it is a sex based trait.  The father passes a Y chromosome to his son.  The gene for color blindness has to come from the mother, she is the one who gives the X chromosome.\nIf the father and son where both color blind, it would be just due to coincidence.

I read once (many years ago) that Native American communities have the highest rate of suicide and depression of any group of people.\n\nI don't think suicide is genetic but a predisposition to depression can be.\n\nAs for how it affects people you might want to look up studies on it. I'm sure someone has looked into this.

I think it is only partly genetic. There are still many other factors that can cause homosexuality... hormonal imbalance, the people a person associates during his/her lifetime, and many more... People may think that it is passed from parent to child probably because they've seen some homosexual 'traits' on the parent and if the child shows similar traits, they think it is because the child inherited it. I think it is because of the upbringing of the children... I'm not sure about this...

We have common ancestory.  We didn't come from them(that would be akin to saying that someone came from their brother or sister) related-Yes, decended from-No.\n\nThis question seems to be a curious religious "fish hook". In mentioning "came from" in the question it seems to indicate there is a certain level of acceptance that there is such a thing as decendancy, lineage etc(and that it is possible that it could happen between species).  The theory of evolution is nothing more than lineage over the loooong term.  Find some pictures of your ancestors, think about how many generations seperate you.  Set aside for a moment any preconcieved notions you may have, take a good look into the intelligent eyes of a chimpanzee.  Maybe we aren't that different after all.    \n\nDo you look like a monkey?  Yea, and I smell like one too.  ;)

a dominant genetic disorder only requires one copy of the causitive gene, so if one of your parents had one copy of the gene and the other none, you would have a 50% chance of getting it. if its recessive, it takes two copies of the gene to actually have the disease, so both parents would both have to have a causitive gene. so dominant usually affects every generation, while recessives usually skip and are less frequently manifested. thats if its autosomal (meaning not on a sex chromosome). if its X-linked, then it gets more complicated. see the link below (pages 4-9) for more help and examples of diseases.

I think we need to do something about the violations being meted out for using people's names in questions. Honestly.\n\nAnyway, there is some evidence of a so-called "god gene."\n\nHonestly, I don't know quite as much about it as I should, but I'll give you some links. What little I do know is what I read in Time or Newsweek or US News and World Report about a year ago. I don't remember which magazine it was.\n\nhttp://en.wikipedia.org/wiki/God_gene\n\nhttp://www.amazon.com/gp/product/0385500580/sr=8-1/qid=1141532372/ref=pd_bbs_1/102-1832914-4225705?%5Fencoding=UTF8\n\nhttp://washingtontimes.com/world/20041114-111404-8087r.htm\n\nHere you go.\n\nWell, the amazon link won't work, but the book is "The God Gene" by Dean Hamer.

I suffer a rare genetic mutation that renders me completely devoid of all seriousness.  it's as though my funny bone grew completely out of control and encompassed my entire skeletal structure.\n\noh, look!  a wombat! ;-Þ

I hate to say it (don't tell anyone I said this,but)it's GENETICS.

yes which genes you inherit can go either way. White people can carry recessive black genes and vice versa

MS is not strictly a hereditary disease. However, increasing scientific evidence suggests that genetics may play a role in determining a person's susceptibility to MS. Some populations, such as the Roma, Inuit, and Bantus, never get MS. The indigenous peoples of the Americas, the Japanese, and other Asian peoples have very low incidence rates. It is unclear whether this is due mostly to genetic or environmental factors.\n\nIn the population at large, the chance of developing MS is less than a tenth of one percent. However, if one person in a family has MS, that person's first-degree relatives—parents, children, and siblings—have a one to three percent chance of getting the disease.\n\nFor identical twins, the likelihood that the second twin may develop MS if the first twin does is about 30%; for fraternal twins (who do not inherit identical gene pools), the likelihood is closer to that for non-twin siblings, or about 4%. The fact that the rate for identical twins both developing MS is significantly less than 100% suggests that the disease is not entirely genetically controlled. Some (but definitely not all) of this effect may be due to shared exposure to something in the environment, or to the fact that some people with MS lesions remain essentially asymptomatic throughout their lives.\n\nFurther indications that more than one gene is involved in MS susceptibility comes from studies of families in which more than one member has MS. Several research teams found that people with MS inherit certain regions on individual genes more frequently than people without MS. Of particular interest is the human leukocyte antigen (HLA) or major histocompatibility complex region on chromosome 6. HLAs are genetically determined proteins that influence the immune system.\n\nThe HLA patterns of MS patients tend to be different from those of people without the disease. Investigations in northern Europe and America have detected three HLAs that are more prevalent in people with MS than in the general population. Studies of American MS patients have shown that people with MS also tend to exhibit these HLAs in combination-that is, they have more than one of the three HLAs-more frequently than the rest of the population. Furthermore, there is evidence that different combinations of the HLAs may correspond to variations in disease severity and progression.\n\nStudies of families with multiple cases of MS and research comparing genetic regions of humans to those of mice with EAE suggest that another area related to MS susceptibility may be located on chromosome 5. Other regions on chromosomes 2, 3, 7, 11, 17, 19, and X have also been identified as possibly containing genes involved in the development of MS.\n\nThese studies strengthen the theory that MS is the result of a number of factors rather than a single gene or other agent. Development of MS is likely to be influenced by the interactions of a number of genes, each of which (individually) has only a modest effect. Additional studies are needed to specifically pinpoint which genes are involved, determine their function, and learn how each gene's interactions with other genes and with the environment make an individual susceptible to MS.

It varies.\n\nIn some cases, a change in the genetic material is noticeable immediately.  For example albinism, or lack of pigment.  This genetic trait can be passed on and it is obvious.\n\nOther cases might require changes in more than one gene or DNA site to become obvious.  These changes can remain hidden for generations before the change becomes apparent.  Other mutations, such as male pattern balding, are not expressed in every generation, but often seem to skip a generation.\n\nThere are also mutations that are so sever as to cause the individual to not be viable.  Infertile plant seeds and bird & animal eggs or still-birth mammals can be examples of non-viable mutations.

It can be either.\n\nIt most commonly exhibits familial transmission consistent with autosomal dominant (AD) inheritance (approximately 90%), but X-linked (5-10%) and much less commonly autosomal recessive (AR) or mitochondrial inheritance have been reported.

Some evidence suggests it, but no direct link has been discovered as of yet.  I, personally, don't believe there are direct genetic involvments with any addiction.  Genetic predispositions to addictive behavior, maybe, but not to any particular type of addiction.

Wow, it is amazing how much the exact wrong answer has influenced the answers here, behavior is certainly influenced by genetics.  Consider what a gene does, it makes a protein, possibly a neurotransmitter, and that effects the way we think, the way we feel, how intelligent or aggressive we become, how frustrated or whether or not we have feelings or empathy for others.  \n\nThe genetic factor governing behavior is so powerful that it has been spotted in every single study that looked for it.  Yet for some reason the faith in a nurturing environment seems absolute.  It is wishful thinking, however it is true that a good environment can armor one against and work as a deterrent to inherited antisocial tendency, it does not take away the tendency though.
