OMG I Want A Twin!

So today will be my first blog post at my new school, that I absolutley love! I will be talking about twins, but not just twins and how they are made or thier process of birth, but the different types of twins. Im so excited! There are indentical twins, fraternal twins, and also conjoined twins, which is something I find quite disterbing. A while ago I used to wonder, how does one person have a duplicate of themselfs? I finally found out a while later from my mom that they're called twins, but that was a while ago, she probably told me way more discriptive imformation then just saying twins. Once I think about it.. yeah she definantly told me way more information then that! Gosh I love my mom. Anyways, I'm getting off topic, let me move on to the leason..

[COUGH, COUGH, COUGH]

"Ladies and gentleman, boys and girls, I give you IDENTICAL TWINS"!!! 

                                                            [the Olsen Twins]

    The picture you see above are two well known celebraties, Mary Kate and Ashley Olsen. They are also [as you can see] identical twins [correct term monozygotic]. Identical twins are developted when the fertilized egg splits. They then turn into individual embryos. Since the embryos formed from one single egg/sperm combination, each embryo share the same genetic orgins. In other words, the have the same DNA. Oh, wow doesn't this just make you want to be re-born and identical to yourself? I don't know about you, but im fasinated.

Have you ever wondered maybe Heyy, I want a twin? Well maybe you do. Sometimes two eggs are fertilized by two seperate sperm. Usually women only realese one egg in an ovulation cycle but ocationally some women realese two eggs. This whole process is the making of fraternal twins [also known as Dizygotic]. 

          The two men you see above are what we call fraternal twins. They share some similar characteristics and have some different. For example: the brothers you see here have the same skin tone, and hair, plus they both look good in collared shirts. But if you look at them they don't look identical like the Olsen Twins. If you observe the one on the our left has a smaller chin, while the one on our right has a bigger chin. Also [now im just being very observent] but the one on the left has a bigger forhead. No affence toward that guy I'm just stating the obvious. This is how you determine weather or not they are identical or similar. But remember they'll always be the same age. But not exactly, maybe by a minute or two. Oh the race is one! I was just thinking, what if i had a unknown or longlost sister or brother that's my twin? Which reminds me. Your fraternal twin doesn't nesseccaraly have to be the exact same gender, you could be a girl and your twin could be a boy [and the other way around]. Ummmmm, I'm starting to not want a twin anymore.

        And last but not least conjoined twins.

This is when you are born with either and extra body part or even a head. This doesn't happen very often, 1 once every 200,000 live births. They develop from the same fertilized egg and genetically share the same characteristics. Ewwwwieee, I can't do this no more! BYEEEE (: I'll be back soon

And if you want to be really amazed. Below you will find a video of two amazing twin Dancers..
