What is the interacting role of genetics and environment on human health?

in general,\nphenotype = genotype + environment\n\nor in layman's terms,\nman = genes + lifestyle

Genetics and evolution.

Not necessarily. It could be a mutated gene, a side effect of another health issue, or it could be a recessive gene thus making it in fact genetic.

Umm race is a part of genetics.  Food intake, and activity level also play a part.

I am a social-cultural anthropologist and the debate between "nature vs. nurture" will always be a heated topic (well in the anthro circle lol)\n\nI believe, after studying both biology and anthropology, that there is no way to separate the development of a person's character from their environment nor can you separate the environment from a person's character.\n\nWhat we do will affect our environment, and what happens to our environment will affect us. Studies have shown, that indeed, our environment (which constitutes not just physical living quarters but our society also) has a physical affect on our bodies development.\n\n*I would like to add for the "environment only" people's responses that if indeed all that our character was based on environment alone, everyone within the same environment would have the same character. This is logically impossible. We are born with innate differences in character (innate being a very touchy word to use) that make us react differently to life. Such differences can be seen with children who have autism.*\n\nWe, of course, will continuously have an impact on our environment...so to answer your question in 1 sentence:\n\nWe can not develop the character we have without both innate physical traits or our environment present =)

No. Mutations are the ultimate source of genetic _variation_, but this random variation is shaped by various evolutionary forces (natural selection, genetic drift, migration, selective mating...).\n\n"If these spontaneous mutations are truly spontaneous than will the environmental changes caused from the worlds industrialization have an effect on the rate and manner of which these bases are put together to form amino's within protein structures which will change our genotype therefore being expressed within our phenotype?" \n--> Most mutations are either neutral (have no effect on fitness) or deletereous (have negative or mortal effects). There are pollutants that can cause increased mutations but those are usually negative and are not incorporated into the gene pool of the human population.\n\n\n"If we evolve to our environment than will the chemicals we put into our ecosystem have a gradual but significant impact on our evolutionary path?" \n--> You mean that we should go on polluting and see if any mutations arise that make us "immune" to our own contamination? I wouldn't recommend that. \n\n"... we may have to save ourselves from ourselves in order to survive by mastering and altering genetics through the deletion of the genes within chromosomes that cause undesirable genetic diseases within the gametes before artificial conception.The next step in mans' evolution is the deletion of bad genes to survive in a tainted world.After technology advances to an even higher level we must master the addition of beneficial genes through advanced genetic engineering."\n<-- We cannot do that. It will be a long time before we even begin to understand how our genome works (relatively tiny parts are know now). If we ever do that (outside movies) then I'm afraid it won't be a very equal world for everyone. \nAnd in addition: there is no such thing as GOOD or BAD genes. Any trait is well adjusted only with respect to its environment; by eliminating some characteristics that you deem "bad", you might be erasing the chance to adapt to future changes. That's why the conservation of genetic diversity is important.

Cancer is not strictly hereditary, but genetics does play a part, and the size of the part it plays varies from one kind of cancer to another.\nCancer is in fact body cells growing out of control, which is triggered when enough mutations of the cells have accumulated. Mutations may be caused by carcinogens, which are various things that can lead to cancer, for example tobacco, radioactive substances, hepatitis B virus. Mutations occur in our bodies every day, and that is why our body cells die every day to lower the possibility that they accumulate enough mutations to become cancerous.\nHowever mutations in germ cells (the reproductive cells like ova and sperms) may be given to offsprings. This means that offsprings now have more mutations to start with, and so easier to accumulate enough mutations to have cancer. Hence, we can see clustering of various types of cancers in families, such as colorectal cancer, cervical cancer, lung cancer. (but lung cancer may also be due to second hand smoke from one family member that smokes)\nEven though cancer is not classified as a hereditary disease (contrary to cystic fibrosis, colour blindness etc), genetics does play a part in the development of cancer.

I don't know how helpful my answer will be, but i will keep it short. The real answer for this question will be in a Biology textbook. \nBasicly, Genes are sequences of chemical pairings in a protein called DNA, found in the Nucleus of all living cells. There are many parts of a gene, each consisting of segments of these pairs of chemicals. When a special protein called a ribosome 'reads' these sequences, it produces other chemicals, proteins and enzymes which regulate your body's functions. \nFor example, There is a gene in your body for the color of your hair. If you are a red-head, your genes code for the release of more red-pigment by your hair follicles. \nThis control can be exerted on anything. Chemicals regulated by genes can stimulate your hypothalmus in your brain, and, for example, make you grow taller, or regulate otehr body functions that affect how you look. \n\nIn your vegetable, a gene might encode for a chemical that prtects it from bacteria or fungus, possibly slowing the decaying process caused by these organisms.

different factors are involved in someone who abuses substances, and genetics is one of them. It does not mean, though, that it's a genetic condition, but genetics is involved in it.

nothing but two reasons\none is genetical. you cannot change\nother is the environment . bad water,(salt water),over usage of chemicals,shampoo etc

no.\n\nCurrrent scientific studies show that its genetics AND environment....not one or the other.

You'll have to be more specific as to which chemicals you want to know about.  The building blocks of Genes are Organic Structures / chemicals as are the individual nucleic acids and nitrogenous bases.     \n\nPlease see my sources for more information.

1) So far it is not known how many diseases, such as cancer, form in the body. So, as far as we know, only luck prevents you fomr getting many diseases.\n\n2) Many health problems are inherited through genetics. Maybe your parents give you an illness that runs in the family, maybe they don't. You have no control over it.\n\n3) I can't think of a third one, I hope the other 2 helped.

Google that and you will find as I did that there is a wealth of information on external environment analysis within health care!!!\n\nGood Luck!!!

Pick one environment vs. genes. Some children with other disabilities like ADHD, without proper care and treatment can become Oppositional and or conduct disorders. Sometimes it can be the cause of environmental issues, which in my opinion is harder to discover, because they don't just tell you.

genes do not cause sickness bacteria, germs and virusis. Genes just can make you more able to catch certain things or diseases.
