具有“父子相传”的特点

多基 因遗 传病
染色体 异常遗
传病
遗传特点
①常表现出家族聚集现象 ②易受环境影响 ③在群体中发病率较高
往往造成较严重的后果, 甚至胚胎期就引起自然流 产
实例 冠心病、哮喘病、 原发性高血压、 青少年型糖尿病
21三体综合征、 猫叫综合征
(2)生命观念——结构与功能观 上题D项染色体异常遗传病患者的后代是否一定患该遗 传病? 提示:不一定。染色体异常遗传病患者可能产生染色体 正常的配子。
【误区警示】先天性疾病≠遗传病 (1)先天性疾病中的许多疾病与遗传病有一定关系,但 不等于说先天性疾病都是遗传病,如先天性心脏病等。 (2)遗传病不一定是一生下来就表现出来,如男性秃
【思考·讨论】 1.若某遗传病由一对同源染色体上的两对基因控制,该 遗传病是否遵循孟德尔两大遗传规律?试简要分析。 (科学思维)
提示:遵循分离定律,不遵循自由组合定律。因为等位 基因只要位于同源染色体上,就遵循分离定律。非等位 基因必须位于非同源染色体上,才遵循自由组合定律。 本题中的两对基因位于一对同源染色体上,所以不遵循 自由组合定律。
【解析】选A。多指为显性遗传病,白化病为隐性遗传 病,前者发病率较高,A项错误。多基因遗传病的特点是 容易受环境影响、在群体中发病率高,B项正确。患白 化病且患血友病孩子可能为男孩(设基因型为aaXbY), 其父亲可能是白化病基因携带者(Aa),其血友病基因所 在的X染色体来自母方,故父亲基因型可能为AaXBY,表
现正常,C项正确。染色体变异不改变基因的种类,只改 变其数量和排列顺序,D项正确。
【素养·探究】——母题追问 (1)科学思维——演绎与推理 上题C项若该患白化病和血友病的孩子父母均正常,其 父母再生一个两病兼患孩子的概率是多少?

其他班干部策划了“走进敬老院”活动, 并且多次与 工作人员协商,这也提升了我与人沟通的实践能力。这 些宝贵的工作经验教会我做事的方法,让我能更好地胜 任学生会主席的职务。

【技法提炼】
微笑着面对生活 如果挫折是那刺人的荆棘,微笑 就是那高洁的百合。如果失败是那 陡峭的崖,微笑就是那平坦的阳 光道。如果忧郁是那光秃的槐树,微笑就是那昂首北国 的青松。
是的,微笑永远是美好的,它能抚平你精神的创伤; 能使你精神焕发,充满自信……
冰心是蜚声海内外的文学家,她经历过苦难生活的 考验,写下了几百万字的作品,一生都在繁忙中度过。 她一直活到99岁,成为世纪老人。她在谈到自己健康长 寿之道时说:“对我来说,保持健康的方法不是高营养, 吃补药,而是一句话‘在微笑中写作’。我写了一辈子, 虽然我年纪大了,但从未停笔,因为我的心情总是乐观 的”。
就特别具有民主作风。因此,我的口号是“做一个彻底 的平民班长”。班长应该是架在老师与同学之间的一 座桥梁,能向老师提出同学们的合理建议,向同学们传 达老师的苦衷。我保证做到在任何时候、任何情况下, 都首先是“想同学们之所想,急同学们之所急”。当师 生之间发生矛盾时,我一定明辨是非,敢于坚持原则。
特别是当教师的说法或做法不尽正确时,我将敢于积极 为同学们谋求正当的权益。
以前的我特别忧郁、特别感伤,仿佛被剥夺了“微 笑权”。愁眉苦脸和唉声叹气让我的生活失去了色彩。 也许失去以后才懂得它的可贵,在没有微笑的日子里, 我是那么孤独,那么郁闷,就好像折了翅膀的小鸟,怎么 飞都飞不高;现在我插上了翅膀——微笑,可以在广阔 的天空下振翅翱翔。
