what are adoption and twin studies?\nWhat are the types of twins?\nWhat is the nature vs. Nurture debate?

In adoption studies, psychologists studied how much children's IQ was related to their parents. For example, was the biological child's IQ closer to their parent than the adopted child to their new parent? They found that biological children have a closer IQ to their biological parents than do adopted children to their new parent. So that means that nature must have played more of an important role than nurture. However, when the adopted child came from an impoverished environment and was put in a better home with better parents, their IQ increased dramatically, which means that nurture still plays a great role in influencing a child's IQ.\n\nThe types of twins are fraternal or identical.\n\nThe nature vs. Nurture debate is about whether you become the person you are because of (nature) biological factors (meaning you are born with a certain IQ and certain characteristics that you inherited from your parents and cannot change) or because of (nurture) environmental factors such as how your parents raised you, if you were in an abusive or good home, etc.

Identical twins come from one egg being fertilized and then splitting in two.  Non-identical twins come from two separate eggs being fertilized.

Great topic.. I personally LOVE genetics, and geneticists have come a loooooong way. Here's a few websites with good articles for you to read:\n\nhttp://archive.greenpeace.org/geneng/reports/food/intrfood.htm\n\nhttp://uk.encarta.msn.com/text_781566628___4/Genetic_Modification_of_Food.html\n\nhttp://www.planetpapers.com/Assets/835.php\n\nhttp://www.ifst.org/site/cms/contentChapterView.asp?chapter=1\n\nhttp://www.ourfood.com/Genetic_modification_food.html\n\n\nHope these help!

Your "soul"?  What are they teaching in biology class these days? :-)\n\nLook, a person and their clone would be no more alike than two normally occuring identical twins.  In fact, genetically, that's exactly what a clone is ... just an identical twin.  They *look* alike, and may have some similar propensities (they may both be naturally talented at math, say) ... but other than that they are two completely independent human beings.  They will have different experiences ... that makes them different.\n\nAs for your "soul", biologists are happy to leave that to the spiritual folks.  Biologists have no opinion either way.

Wow there are alot of choices that have different views. Not sure what you are looking for but here are some debates:\n\nAbortion, gays adopting, spanking children, immigrants, etc. \n\nI will still think about this one and get back to you.\n\n\nETA: Polygamy, Same sex marriages

Yes! I have an adopted daughter and I have twin girls. I love all the same but there is a difference in the closeness I think because I gave birth to the twins

Fraternal twins can still look alike. Fraternal just mean that they each were conceived in separate eggs. Identical twins are conceived from one egg that splits into two.

Both. Your genetic makeup will determine a large number of factors in your makeup/development. Environment also plays a large role. If you look at the studies on identical twins, you'll see that they are extraordinarily similar for the first few years, but then start developing differences. These variations won't be physical, since those are genetic, but more behavioral.

This is like asking Why are there so many different kinds of flowers, there is no one answer for this question. Sometimes the mother makes poor or uneducated choices during pregnancy or isn't aware of being pregnant; poor neutrition, smoking, drugs, exposure to certain drugs and chemicals will negatively affect the developing baby. Generally in this situation there is damage to the tissues of the developing baby stopping things from proceeding normally.  \n\nSometimes, genetics affect the embreo in the same way identical twins develop. Genetics are the "roadmap" that tells the cells what to be and where to go. Sometimes genetics tells the egg to seperate making two identical babys, but sometimes there are flaws in the "roadmap"   and things don't develop or don't develop properly.  \n\nSometimes there is no reason at all for the disability. It's a sad start to life but good parents will help the child to make the most of their situatin and lead a productive life.

I'm not sure if this is what you're looking for, but check out this site.  It give some pretty interesting book ideas.  \n\nhttp://www.comeunity.com/adoption/books/0multiracial.html

why don't you start with this:\n\nhttp://genealogy.about.com/cs/adoption/a/adoption_search.htm\n\nWe just found out my mother in law had a baby in the late 50's.  She was contacted by her son (who lives in Australia) and they've been corresponding ever since.  She was 'forced' to give up her child, and no one knew about him except my MIL and her siblings.  It was a very scary thing for my MIL to 'confess' to her family there was another child before them.  But it's a great weight off her shoulders.  She is happy to know her son had a good life and is not angry with her for giving him up.

They're not always opposite gender. "Fraternal twins" can mean the opposite of "identical twins". Sometimes called dizygotic, it means that although they are twins, they developed from two different eggs, not one. They therefore share only 50% of their genes (the same as any two non-twin sibs), rather than 100% that identical twins share.

Genetics of the fruit fly drosophila (Mendeline genetics)\n\nAn essay on Darwin and his discovery of Natural selection would be good and interesting reading.\n\nHow do finger prints work? Including the history of, and perhaps a discussion on the fact that identical twins do not have identical finger prints.\n\nOver farming/fishing, how humans are quickly using up the environment and resources of the planet.\n\nThe extinction of the Dinosausrs.\n\nThe phenomenon of the Peppered Moth and Industrial melanism.\n\nDepends what area you are interested in, you can pick something you find fun and do some research on it, don't think of it as hard, think of it as an opportunity to do something you enjoy and show your markers how much you enjoy it by researching it.

Yes, they are. Until we learn to care for the ones already exisitng, we should hold off on creating more of our own. (Just a personal observation.) Perhaps some of these families who like to pop out kid after kid should adopt one (or several).

>>>>>I'm male, so I shouldn't be displaying mosaicism...\n\n\n\n\nAre you sure? Have you tested whether you are a natural chimaera? (Now that could be a cool research project for a molecular bio major). Nobody is quite certain how common chimaerism is in humans but best guesses put the figure at greater than 1 in 100.\n\nAny history of twins on your family?
