屌丝夫妇生高富帅的概率？这是期末考题！ Prick silk couples GaoFu handsome probability?This is the final exam!

八中“一诊”模拟题玩新花样，专业人士认为这种接地气的出题方式值得提倡 BaZhong"A diagnosis"Simulation problem play new tricks,Professionals believe that the ground gas sets the topic the way is worth advocating

　　迈入高三，免不了每天与各科试卷打交道。但如果你在数张晦涩的黑白题目间瞄到一道有关真屌丝与高富帅的论述，眼前会不会为之一亮呢？有幸尝试这道题目的八中学生就晒起了幸福，“做题还从没这么嗨过！”

Entering high school,Avoid all papers every day and deal with.But if you in a few zhang obscure black and white between subject aim to a relevant real prick silk and GaoFu handsome discussed,Eyes will shine for it?To try this problem BaZhong of students is drying up happiness,"Do problem never so hi over!"

试题现屌丝与高富帅之争 Item now prick silk and GaoFu handsome rivalry

　　“真屌丝是找不到配偶的，其他均能找到门当户对的配偶，考题与时俱进地简直无法让人直视……”近日，一张重庆八中一诊模拟题（十）的截图在微博上“浮出水面”，试卷第3题有关屌丝和高富帅基因的讨论，令众多网友眼前为之一亮。

"Really good silk is could not find the spouses,Other all can find spouses of equal status,The questions can't let a person look in the eye..."recently,A chongqing BaZhong a diagnostic simulation problem(ten)The screenshots in micro blog"surface",The third question papers about prick silk and GaoFu handsome gene discussion,Make many users as one of the bright eyes.

　　题目中称，科学家发现传说中的屌丝基因位于人的第十对染色体上，已知屌丝的性状由一对等位基因控制（用A，a表示），且遵循分离定律。现有一对屌丝夫妇生出了一个高富帅。则该夫妇再生出一个孩子是高富帅的概率是__。若基因型是纯合子的屌丝叫真屌丝，真屌丝是找不到配偶的，其他均能找到门当户对（即基因型相同）的配偶，如果该夫妇又生了一个男屌丝，则这个男屌丝带给该夫妇的小孙孙是高富帅的概率是__。

Said in a subject,The scientists found that the legendary prick silk gene is located in the first ten people on a chromosome,Known prick silk character by a pair of alleles control(With A,Said a),And follow the law of segregation.Existing a prick silk couples living a GaoFu handsome.The couple regenerate a child is GaoFu handsome probability is __.If the genotype is homozygous prick silk through prick silk,Really good silk is could not find the spouses,Other all can find be matched for marriage(That is the same genotype)spouse,If the couple and gave birth to a male prick silk,The male prick ribbon to the couple is her new grandchild GaoFu handsome probability is __.

学生别只盯着高富帅 Students don't stare at GaoFu handsome

　　重庆八中高三理科（2）班的陈彦彦表示，上周下午的生物课上，老师徐鹏飞抱着试卷走进教室。讲台下抱怨声一片，但徐鹏飞却露出“奸诈”一笑，“慢慢做，题目中有惊喜哦！”

Chongqing BaZhong three science(2)Class ChenYanYan said,Last week the afternoon biology class,The teacher came into the classroom XuPengFei hold papers.Under the platform moans a piece,But XuPengFei but show"false"A smile,"Slowly do,The topic has a surprise!"

　　每名同学拿到试卷后，原本沉闷的班级立即热闹开来，原来试卷第一道题即是以班级其中一名同学举例，来分析乙肝体检结果。当大家做到第3题时，全班同学彻底“崩溃”，不少同学开起了玩笑，“老师，真屌丝当真找不到配偶？”

Each students get after test,Originally depressing class lively open immediately,The original papers the first question is one of the students in the class, for example,To analyze the second liver medical results.When you do the third problem,The whole class thoroughly"collapse",Many students poked fun,"The teacher,Really good silk really can't find spouses?"

　　陈彦彦称，从当天生物课上的气氛来看，同学们都乐于尝试把生活笑点与课本知识点结合在一起的题目，“做题还从没这么嗨过！”但后来，由于忽视了性别问题，陈彦彦还是在该道题目的概率运算上出了错，“除了高富帅，不是还有白富美吗？”

ChenYanYan says,From the day of biology class atmosphere to see,The students are willing to try to make life smile point and textbook knowledge together in subject,"Do problem never so hi over!"But then,Due to ignore the gender issues,ChenYanYan or in the problem of probability operation on the wrong,"In addition to GaoFu handsome,Isn't there BaiFu beautiful?"

出试题让学生轻松一笑 The questions let students easily a smile

　　出题人徐鹏飞是重庆八中高三年级理科班的生物老师，今年25岁，学生都叫他“飞哥”。

On one XuPengFei is chongqing BaZhong grade three in science class biological teacher,This year 25 years old,Students are told him"Flying elder brother".

　　“飞哥”表示，此题并非原创，而是根据微博上一道类似的生物题改编而成。之所以把这道题选入自编的一诊模拟题中，“飞哥”嘴角一抿，“高三学生平时学习压力相对较大，一天做题都做疲了。把生活中的笑与学科考点结合在一起出题，不仅能巩固学科知识，还能让他们放松放松，在趣味中学习。”

"Flying elder brother"said,This problem is not original,But according to the micro bo on a similar biological problem adapted.Is the problem of a selected designed diagnostic simulation in question,"Flying elder brother"Corners of a sip,"High school students study at ordinary times relatively large pressure,One day become a problem do the arrived.The life with smile subject test set together,Not only can consolidate subject knowledge,Still can let them relax,In the interest of learning."

　　“飞哥”称，这道题目实际上涉及高二下学期的生物遗传概率算法。面对网友各自迥异的答案，“飞哥”向记者讲解起该题的思路来：由题目中一对屌丝夫妇生出了一个高富帅可知，屌丝是显性基因A控制，高富帅是隐形基因a控制，屌丝夫妇基因型为Aa，生下的高富帅基因型为aa。这对夫妇再生一个aa的几率为1/4，因为aa有可能是高富帅也有可能是白富美，而生男生女的概率各为1/2，所以生下的aa是高富帅的概率是1/4X1/2=1/8。

"Flying elder brother"says,The problem involved in the second semester of high biological genetic probability algorithm.In the face of the net friend our different answers,"Flying elder brother"Explain to the reporter on this topic of thought to:The topic of a prick silk couples living a GaoFu that handsome,Prick silk is dominant gene A control,GaoFu handsome is invisible gene a control,Prick silk couples for Aa genotype,Born of the GaoFu handsome genotype for aa.The couple regeneration a aa chance for 1/4,Because aa may be GaoFu handsome may be BaiFu beauty,Born a male and female the probability for 1/2,So gave birth to the aa is GaoFu handsome probability is 1/4 x1/2 = 1/8.

　　再生一个男屌丝有1/3的几率为真屌丝AA，2/3的几率为一般屌丝Aa，这个男屌丝Aa有2/3的可能性找一个门当户对的配偶Aa，再生一个高富帅aa（男）的几率为前面的2/3x1/4x1/2=1/12，即这个男屌丝有1/12的概率为这对夫妇带来一个高富帅的小孙孙。

Regeneration a male prick silk has a third of the chance to true prick silk AA,Two-thirds of the probability for general prick silk Aa,The male prick silk Aa two-thirds of possibility to find a spouse Aa of equal status,Regeneration a GaoFu handsome aa(male)Chance for front two-thirds x1/4 x1/2 = 1/12,That is the man prick silk has 1/12 of the probability for the couple to bring a GaoFu handsome her new grandchild.

接地气的出题方式值得提倡 Ground gas sets the topic the way is worth advocating

　　八中高三生物教研组组长荣海表示，从学科专业角度来讲，徐鹏飞出的这道生物题并不严谨，没有真正体现基因对生物性状的控制。“但学生往往在遗传变异和遗传概率的计算方面存在畏难情绪。”荣海指出，从学生的角度，把他们感兴趣的内容和知识点结合在一起，有利于激发学生主动学习的动力。荣海认为，从目前在学生中的反响来看，这类接地气的出题方式值得提倡。

BaZhong high school biology teaching and research group leader RongHai said,From the point of professional disciplines,XuPengFei out of the way biological problem is not precise,Not really reflect genes on biological properties of the control."But students are often in genetic variation and genetic probability calculation are the fear of emotions."RongHai pointed out that,From the point of view of students,They are interested in the content and knowledge together,To stimulate the students' active learning motivation.RongHai think,From the current response of the students come to see,This kind of ground gas sets the topic the way is worth advocating.

可探讨类似教学方式的利弊 Discusses the advantages and disadvantages of the similar teaching method

　　重庆教科院副院长王玮虹表示，老师以学生感兴趣的事物来喻指书本上的知识点，从教学上看有失严谨，但通俗易懂的方式激发了学生的学习兴趣，体现了教育者以学生为本的理念。“一棒子打死或盲目的追捧均不利于教育的改革。”王玮虹指出，八中这位老师的出题方式值得鼓励，但不要流于形式，教育工作者们不妨一起来探讨该类型教学方式的利与弊，以追求更长远的意义。

Chongqing to teach science institute vice President wang hong said,The teacher to students interested in things to passing on the books of knowledge,From teaching see beneath rigorous,But straightaway way stimulate the learning interest of the students,Embodies the educators to students for the idea."A bonzi killed or blind chase after hold in both hands were detrimental to the education reform."Rainbow wang pointed out that,BaZhong the teacher sets the topic the way should be encouraged,But don't become a mere formality,Education workers might as well come into the type of the advantages and disadvantages of teaching methods,To pursue more long-term significance.
