Hah. We're studying twins in Child Development right now. x33
Ugh. I hate that class. D:<
Let me see if I can help you. I don't have a twin, but...
Do fraternal twins share the bond that you hear identical twins have?
We didn't really study that aspect of twins, but I don't think there is much of a difference in bonding, you know? Identical twins can grow to hate each other, just like fraternael twins can be incredibly close. You have a best friend, don't you? Or a friend at the least. You've bonded, right? And it doesn't have anything to do with your when you were born or who you were born to. It has to do with how you get along with each other, which depends on the nature of each twin, which is different for every person.
Does your identical twin look different then you?
I don't have a twin. (I remember when I was younger I wanted a twin sister. I would pretend we'd dress alike every day. xD) But identical twins look almost, well, identical, because the same sperm fertilized the same egg, giving the twins the same genetic makeup. So yes, identical twins always look alike.
Does your fraternal twin look the same as you?
Fraternal twins can look alike, but they don't have to. Fraternal twins are created when the mother releases two eggs during ovulation, and both are fertilized by two different sperm. So, therefore, even though the two shared the room together for about nine months, their genetic make up is still completely different. So they don't usually look like an exact duplicate of each other - just like any brother and sister, or whatever other gender combination.
Can you give me any other info about you and your twin?
Um,, if you have any other questions I would be happy to help you answer them.
