But, things like environmental influences change the way the twins look. For example, in a study done by Carl Bruder, one twin was missing some genes on particular chromosomes that had an indication for a risk of leukemia, which that twin did suffer. The other twin didn't. Identical twins have the same genome, so they don't have any genetic differences. The only differences come in the environment, which was shown in the leukemia example.]]> 2017-10-24 20:19:56 UTC https://padlet.com/8020325/u5z1oujp1gdb/wish/200195323 8020325 https://padlet.com/8020325/u5z1oujp1gdb/wish/201351726 https://www.scientificamerican.com/article/identical-twins-genes-are-not-identical/

Each twin usually has its own placenta. Fraternal twins (like other siblings) share about 50 percent of their genes, so they can be different sexes.]]> 2017-11-06 22:36:40 UTC https://padlet.com/8020325/u5z1oujp1gdb/wish/204151562 8020325 https://padlet.com/8020325/u5z1oujp1gdb/wish/204154695 While there are some genetic differences with different twins, most physical and some genetic things are the same, although with identical twins share the same genome, meaning they don't have genetic differences, fraternal twins have 50% identical DNA, the other 50% is different.]]> 2017-11-06 22:51:13 UTC https://padlet.com/8020325/u5z1oujp1gdb/wish/204154695 8020648 https://padlet.com/8020325/u5z1oujp1gdb/wish/204355886 Identical Twins share the same DNA that's why they look alike but they aren't exactly alike. They can be hard to tell apart but if you look closely, you see differences. (maybe one has more freckles than another.) Identical twins have physical differences because of both nature and nurture matter. The environment plays a big part when it comes to identical twins for example what you eat, how much exercise you get, how much time you spend outside rather than inside, eating healthy rather than unhealthy and other things can happen during your life may be getting in a car crash and having a scar.  In some cases, as identical twins get older they start to have differences and they don't look the same and while there are still things that the twins will have in common there will be obvious differences between the two.
