雙胞胎會有自己的語言嗎？ 答案是會的。 科學表明，雙胞胎之間會有自己獨特的語言和交流方式，並且父母是無法破譯的。

雙胞胎可分為兩大類：異卵雙胞和同卵雙胞。

異卵雙胞胎 Fraternal twins

顧名思義，異卵雙胞是由兩條精子分別與兩粒卵子結合而來，兩個胚胎各自帶著不同的遺傳基因，兩個胎兒的性別也不一定相同；一男一女的「龍鳳胎」就是異卵雙胞胎了。

通常被人们称为假双胞胎”。

即使是相同性別，異卵雙胞的「孖仔/孖女」外貌也不會完全一樣。

異卵雙胞的胎盤屬於雙絨毛膜雙羊膜類，每個胎兒均有獨立的絨毛膜和羊膜；意思是在媽媽的子宮內，兩個胎兒各自有「獨立的房間」，所以他們互相干預的機會很低。

同卵雙胞胎 Identical twins

同卵雙胞則是由一條精子與一粒卵子結合而來，受精後的胚胎一分為二，分裂出來的兩個胚胎有相同的遺傳基因，兩個胎兒的性別也相同，一定不是「龍鳳胎」。

即他们具有相同的基因，所以出生后的双胞胎性别相同、容貌相似，血型、体质等也相同，这通常被人们称为真双胞胎”。

同卵雙胞的「孖仔/孖女」外貌會完全一樣。同卵雙胞的胎盤類型又可細分為雙絨毛膜雙羊膜、單絨毛膜雙羊膜或單絨毛膜單羊膜三種。

單絨毛膜單羊膜類是最危險的，因為這類雙胞胎的兩個胎兒沒有羊膜分隔，在媽媽的子宮內沒有「獨立房間」，所以他們「打架」或互相干預的機會較大。他們的臍帶可能會纏結，導致缺氧。最極端的狀況就是聯體孖胎，俗稱「連體嬰」。

單絨毛膜雙羊膜類的雙胞胎，則會出現雙胎輸血症的風險，其中一個胎兒會搶去另一胎兒的血液。

18%的同卵雙胞胎有不同的優勢手：比如哥哥擅長左手，弟弟可能擅長右手。

雙胞胎會有相同的指紋嗎？ 其實對於雙胞胎來說，他們可以有一樣的臉、一樣的生日、性格、甚至DNA，但是相同的指紋是少之又少，但是生命總會有奇蹟，說不定世界上某個角落會有相同指紋的雙胞胎，只是這種概率非常之小。

幾乎一半的雙胞胎都有自己的語言：為了相互交流，大約40%的雙胞胎創造了一種只有他們自己理解的語言。

雙胞胎會有不同的生日嗎？ 會有不同生日的雙胞胎。 比如第一個寶寶在23：59出生，而另一個在第二天的0:00出生，這就擁有不同的生日啦！

雙胞胎有心電感應嗎? 答案是有的!

mental telepathy 心電感應 心電感應的天賦是否存在這些人的潛意識中，和所傳達的訊息可以被儲存並且由光子傳輸給對方．在雙胞胎的實驗當中，許多系列的測試已非常清楚證明此類的兄弟可以相互溝通，而溝通的方式卻無法以正統物理學去加以解釋的，雙胞胎有著完全相同的遺傳因子，很明顯地會大大增加心電感應的技巧。

實事上，縱然感受不是很強烈但我們每天的日常生活亦會有心電感應的感覺

一對雙胞胎被分離在不同的孤兒院彼此互不認識，卻試圖著和對方聯繫而終於找到對方，特別是在雙胞胎其中一位遭遇到危急狀態時，心電感應的潛在力量非常戲劇性的被發揮出來．

個人例子: 在我幼稚園的時候,有一次我開開心心和其他小朋友玩玩具莫名其妙突然大哭,老師也百思不得其解...後來老師問我我只說我要找妹妹,老師帶我到妹妹的班級,發現妹妹一直哭。 我哭因為妹妹在哭。

爸媽不同種族的話，雙胞胎看起來像是不同種族的機會只有百萬分之一

夫妻 Remi Horder 和 Kylee Hodgson 真的就有一對這樣的雙胞胎寶寶。Kian 是黑皮膚、深咖啡色頭髮、深咖啡色眼珠，但是 Remee 是白皮膚、金頭髮、藍眼珠。

從綜合研究結果看起來，同卵雙胞胎一起出櫃的機會大約在五成左右，而異卵雙胞胎性傾向的相關性就比較低，降到兩成左右；也就是說，當異卵雙胞胎的其中一個出櫃時，另一位也出櫃的機會大約20%左右。

基因愈相同，性傾向愈一致

I definitely think what drives technology companies is the people; because in a technology company it's always about what are you going to do next.

I played golf for 25 years before I made a hole-in-one of any kind. I was on the tour for years before it finally happened. Eventually I made 23, but boy, that first one was a long time coming. It was the price I paid for not shooting at every flag.

Leftist reactions are always histrionic.

I think you have to be what you are. Don't try to be somebody else. You have to be yourself at all times.

I don't think life is absurd. I think we are all here for a huge purpose. I think we shrink from the immensity of the purpose we are here for.

It's a short step from the belief that every child should be wanted to the belief that a child exists to satisfy our wants.

I'm still trying to improve. Everything I can do to improve every part of my game - I'm going to do it.

No other single influence has had so great an impact on this earth as the life of Jesus the Christ.

The sublimity of administration consists in knowing the proper degree of power that should be exerted on different occasions.

If you spend enough time in or around Washington, you'll meet amazing people who work for the government.

Reading develops cognitive skills. It trains our minds to think critically and to question what you are told. This is why dictators censor or ban books. It's why it was illegal to teach slaves to read. It's why girls in developing countries have acid thrown in their faces when they walk to school.

Consider that the overwhelming majority of those 40,000 near-Earth asteroids are small enough to fit on the parking lot at the mall. And while these rocky runts won't cause Armageddon, they could still flatten such popular hominid hangouts as Manhattan or downtown Des Moines.

Television is such a mediocre medium.

Every book I've written has been a different attempt to understand something, and the success or failure of the previous one is irrelevant. I write the book I want.

People will not look forward to posterity, who never look backward to their ancestors.

'The Portrait of Dorian Grey' beautifully articulates how the altruistic part of ourselves clashes with our essentially narcissistic state.

Courtship consists in a number of quiet attentions, not so pointed as to alarm, nor so vague as not to be understood.

Good and Evil Deeds are not equal. repel evil with what is better. Then you will see that one who was once your enemy has become you dearest friend.

For me, relationship is very important. I can lose money, but I cannot lose a relationship. The test is, at the end of a conversation or a negotiation, both must smile.

Loneliness will give you the greatest chance of ever having a beautiful relationship with another person.

I like books that have razor-sharp plotting that snaps and moves along. It's not about the main character being different at the end. I don't want my main character to be different in the end. I still want him committed to his ideas, to be steadfast, true and loyal.

I know what it's like to have a bunch of material that's working that you don't care about. You want to die.

Sometimes his methods are questionable, and even his morals are questionable, but his intention is always to protect Sydney. So in that way I think he's a good parent.
