準媽媽們,看著自己的肚子一天天大起來,你一定會跟孩子他爹爭論肚子裏的孩子會長得像誰的問題吧?雖說相貌遺傳這問題是難預知的,但從科學角度來說還是有一定規律可循的。

XX.XY,誰來決定胎寶寶的智商和相貌?
——身高是誰的遺傳大?
——父母各占一半。

在營養狀況下的前提下,孩子的身高有70%的主動權掌握在父母的手裏,父母的遺傳是決定孩子身高的主要因素,因為決定身高的因素35%來自父親,35%來自母親。假若父母雙方個頭不高,那就要靠寶寶後天那30%的努力了。

——智力是誰的遺傳大?

——媽媽智力有一定的遺傳性,同時受到環境、營養、教育等後天因素的影響。據科學家評估,遺傳對智力的影響約占50%-60%,就遺傳而言,媽媽聰明,生下的孩 子大多聰明,如果是個男孩子,就會更聰明。這其中的原因在於,人類與智力有關的基因主要集中在X染色體上。女性有2個X染色體,男性只有1個,所以媽媽的 智力在遺傳中就佔有了更重要的位置。

為證明此點,我們首先來復習下高中生物知識:男寶寶和女寶寶是怎樣來的?男生是XY,X (卵)是來自母親,Y(精子)是來自父親。女生是XX,X (卵)是來自母親,X(精子)是來自父親。所以生男生女都是先生的錯,不要怪罪媽媽的肚皮不爭氣。

請注意:男生是XY,所以男生的智商全部都是來自母親的遺傳,女生是XX,所以女生的智商是父親跟母親各有一半影響。因為女生的智商是父親母親都有影響,所以會有中和的效應。所以女生智商的分佈會呈現自然分佈(normal distribution),就是倒鐘狀,中間最多,兩邊較少。

然後男生因為是完全只受一方影響,所以男生智商分佈會呈現在偏向在兩個極端。也就是說,男生天才比較多,但是同時,蠢材之中也是男生特別多。

【這個故事告訴我們什麼?】

1. 你要判斷一個男生聰不聰明,看他媽媽就知道了。可是,你又要怎麼判斷一個男生的媽媽聰不聰明?想不出簡便的方法…。

2. 然後我們用機率來算:生男孩的機率= 1/2;生女孩的機率=1/2。生男孩的時候,母親對於男孩智商的影響力 = 1生女孩的時候,母親對於女孩智商的影響力 = 1/2所以說母親跟父親對於下一代智商的影響力(期望值)的比例是:
1*1/2 + 1/2*1/2 : 0*1/2 + 1/2*1/2= 0.75 : 0.25= 3 : 1= 母: 父

所以說,如果你:
1. 是男生,如果你覺得你很笨的話。你千萬要娶一個聰明的女生來。這樣你小孩翻盤的機率還有七成五,人生還是充滿了希望。

2. 是女生,如果你覺得你很笨的話,因為,你翻人家盤的機率有七成五…。啊,我不能再說了…….總之,最近天氣不錯,出去走走。

3. 當你看到一個男生很聰明的時候,則,他父親很聰明的機率是 0% (應該說,就算他父親很聰明,也對他是沒有影響的),可是他母親很聰明的機率是100%。

所以說,如果你在考慮要嫁給一個很聰明的男生的時候,你就要小心他媽媽,可能會是一個很會算計的婆婆。反之,當你看到一個男生很笨的時候,沒錯,他通常會很有錢,這是上帝的安排,上帝為了不讓人類滅亡,所以他會讓很笨的人很有錢,這樣他才能娶到聰明的女生。

—— 性格是誰的遺傳大?—— 爸爸。

性格是父親的遺傳大。性格的形成固然有先天的成分,但主要是後影響。比較而言,爸爸的影響力會大過媽媽。其中,父愛的作用對女兒的影響更大。一位心理學家認為:“父親在女兒的自尊感,身份感以及溫柔個性的形成過程中,扮演著重要的角色。”另有一位專家提出,父親能傳授給女兒生活上的許多重要的教訓和經驗,使女兒的性格更加豐富多彩。

——相貌是誰的遺傳大?

——具體問題具體分析膚色:總遵循“相乘後再平均”的自然法則,讓人別無選擇。

若父母皮膚較黑,絕不會有白嫩肌膚的子女;若一方白一方黑,大部分會給子女一個“中性”膚色,也有更偏向一方的情況。

眼睛:(眼形)孩子的眼形、大小遺傳自父母,大眼睛相對小眼睛是顯性遺傳。父母有一人是大眼睛,生大眼睛孩子的可能就會大一些。

(雙眼皮)雙眼皮是顯性遺傳,單眼皮與雙眼皮的人生寶寶極有可能是雙眼皮。但父母都是單眼皮,一般孩子也是單眼皮。

(眼球顏色)黑色等深色相對於淺色而言是顯性遺傳。也就是說,黑眼球和藍眼球的人,所生的孩子不會是藍眼球。

(睫毛)長睫毛也是顯性遺傳的。父母只要一人有長睫毛,孩子遺傳長睫毛的可能性就非常大。

鼻子:一般來講,鼻子大、高而鼻孔寬呈顯性遺傳。父母中一人是挺直的鼻樑,遺傳給孩子的可能性就很大。鼻子的遺傳基因會一直持續到成年,小時候矮鼻子,成年還可能變成高鼻子。

耳朵:耳朵的形狀是遺傳的,大耳朵相對於小耳朵是顯性遺傳。父母雙方只要一個人是大耳朵,那麼孩子就極有可能也是一對大耳朵。

下顎:是不容“商量”的顯性遺傳。父母任何一方有突出的大下巴,子女常毫無例外地長著酷似的下巴,“像”得有些離奇。

肥胖:會使子女們有53%的機會成為大胖子,如果父母有一方肥胖,孩子肥胖的概率便下降到40%。這說明,胖與不胖,大約有一半可以由人為因素決定,因此,父母完全可以通過合理飲食、充分運動使自己體態勻稱。

禿頭:造物主似乎偏袒女性,讓禿頭只傳給男子。比如,父親是禿頭,遺傳給兒子概率則有50%,就連母親的父親,也會將自己禿頭的25%的概率留給外孫們。這種傳男不傳女的性別遺傳傾向,讓男士們無可奈何。

青春痘:這個讓少男少女耿耿于懷的容顏症,居然也與遺傳有關。因為父母雙方若患過青春痘,子女們的患病率將比無家庭史者高出20倍。

腿型:酷似父母的那雙脂肪堆積的腿,完全可以通過充分的鍛煉而塑造為修長健壯的腿。倒是那雙腿若因遺傳而顯得過長或太短時,就無法再塑,只有聽任自然了。如何在寶寶降生前,優化你的基因?

——我跟老公皮膚都很黑,可我不想生下來的寶寶也是個黑天使。

——黑夫妻想生白寶寶,孕婦可多吃富含維生素C的食物。維C對皮膚黑色素生成有干擾作用,減少黑色素沉澱,嬰兒皮膚會白嫩細膩。

推薦食品:番茄、葡萄、柑桔、洋蔥、大蒜、蘋果等蔬菜和水果,其中以蘋果為最佳。

——我跟老公都是乾性皮膚,一到冬天就很容易乾裂,怎樣才能讓寶寶不受這份罪呢?

——夫妻皮膚粗糙,孕婦應常吃富含維生素A的食物,能保護皮膚上皮細胞,使日後孩子的皮膚細膩有光澤。

推薦食品:蛋黃牛奶、胡籮蔔、番茄以及綠色蔬菜、水果、乾果和植物油等。微

——我家有遺傳黃頭髮的基因,姐姐家的孩子現在一歲頭髮還是黃黃的,我的寶寶會不會也會遺傳啊?

——如果夫妻頭髮不好,孕婦可多吃含有維生素B族的食物,可以使孩子發質得到改善,不僅濃密、烏黑、而且光澤油亮。

推薦食品:瘦肉、魚、牛奶、麵包、豆類、雞蛋、紫菜、核桃、芝麻、玉米以及綠色蔬菜。

維生素A是脂溶性維生素,要注意食用量,不要吃過量。

From pregnant to birth in 90 seconds: Touching time-lapse video shows how mother-to-be changes over timeBy Marcus Barnes

http://www.dailymail.co.uk/news/article-2113407/From-pregnant-giving-birth-90-seconds-Time-lapse-video-shows-mother-changes-time.html#ixzz1oz3WzR7v

A woman and her partner spent nine months working on a video project to document her pregnancy with heartwarming results.

Their time lapse video, simply called Introducing, shows her midriff grow from a rather toned and flat belly to an oversized protrusion towards the end of her pregnancy and, finally, the arrival of their beautiful baby girl.

The well-produced video condenses the whole nine-month experience into just 90-seconds.

It begins with the woman standing up waiting for her partner, who enters the room and plants a kiss on her flat tummy.

They then high-five each other, presumably a rather innocent way to illustrate the conception of their baby girl.
When he leaves the room she turns to the camera and points at her stomach.

We then see a time lapsed set of scenarios as her stomach grows and their pet cats and dogs disappear and reappear in the room around her.

At one point the couple move house, at which time the woman’s partner picks her up and carries her across the threshold of their new abode.

He then disappears and leaves her to continue to grow.

Finally, when she appears about ready to pop, he returns once more – she signals at her watch that it’s time for someone new to join them.

Again getting down on his knees the man kisses the woman’s belly.

This time however, as he kisses her, their baby daughter pops out.

Then they bring her closer to the camera for her first ever close up and her name, Amelie Amaya, flashes up on the screen.

YouTube users have been quick to commend the couple for their nine-month long project.

One user, named alfacinhotube, wrote: ‘Beautiful! A well-conceived, wonderfully executed documentation of a magnificent moment in your lives. Thanks for sharing!’

While a woman with the user name Malleolust said: ‘I’m 7 months pregnant with my first child, a son. This made me cry. Can I blame hormones…? Little Amelie, be blessed.’

And even one male viewer said the video brought him to tears, matstrick wrote: ‘Beautiful… You just brought a grown man to tears!’
