痴線,咁多人識少少就不斷趁機拋書包話因為多左條染色體,一係就一句病徵就當答左,全部都答唔對題。
唔識答就收聲啦

假設多出黎果條chromosome係有A, B, C gene
每個有down syndrome既人都會多左A,B,C gene
咁每個人多左出黎既野都係一樣,所以個樣就會好似

首先前提是人的genotype會影響phenotype. down syndrome嘅人都有3份21染色體嘅遺傳物質。令到佢地嘅phenotype有相似嘅表現,例如會矮,智力發展遲緩。另一方面,down syndrome會影響到面部特徵嘅發展(面部中央會較小發展-midface hypoplasia) 令到佢地會有D異於正常人嘅特徵,例如低鼻樑,瞼裂斜上向外。而我地認人就係認面部中央嘅特徵,所以你會覺得佢地差唔多樣咁。

其實依家唔係未生就check 到嫁咩?
點解仲會有人肯生出黎受苦

有啲人窮 知識水平又低
一係無錢驗 一係唔知有得驗

有啲耶撚驗到都會照要
宗教既禍害

唔係咁簡單

1. 重點在於difference in genes in coding region among all "extra 21st chromosome"

2. 每一位Down syndrome 病人既extra 21st chromosome 一定來自爸爸/媽媽一方
-> 但每一個人既genes in coding region for phenotypic expression 根本唔同,not to mention the extra 21st chromosome(more accurately the extra chromatin since protein synthesis takes place before the duplication of chromosomes)
-> 所以你既推論話各自多A B C唔係完全正確,因為 A B C phenotype 既gene differences vary from ppl to ppl

事實上其實佢地樣貌有分別,但「分別程度」未必我地正常人可以觀察到

但點解有common features(phenotypic expression):

你兩條on9

呢條問題最主要係人既辨認識別能力,其次係咩係唐氏

人係比較難分其他種族既樣貌,例如黃種人少見黑人就會覺得黑人個個一樣樣;而辨認其他物種既樣貌就更難,好多時你撇除毛色,好多時會覺得啲貓或狗個樣係一樣。

而唐氏係比正常人多左條基因,嚴格黎講可以話係另一物種或另一種族,所以普通人就會覺得佢啲似樣,其實純粹係你接觸得唐氏少。

每隔一排就有人問 當年今日

依d先叫做答案
上邊個個講病徵做乜鳩
病徵都算係答案?

嗰d人同
問:點解小明跑得快過火車
答:因為小明跑得快
有乜分別

痴線
上面笑人地係狗果條友係咪痴撚線
定以為自己好風趣?
先天性缺憾都笑人真係好仆街

利申唔係果d唔講得笑嘅人
但攞人地嘅缺憾黎笑我真係覺得好仆街

話人生佢出黎令佢受罪果d
唔好用正常人角度去睇佢地啦

我估計「可能,只係可能」,根本人體21st a pair of homologous chromosome上,differences in genes in coding region among all individuals 分別唔大gwa

Gene coding region就算喺唔同individuals都係conserved
個code會可能有啲唔同,但個sequence同個位置基本上係conserved,稱為consensus sequence
某啲gene嘅sequence of coding regions直頭係conserved across species
所以down syndrome patient個樣會似係因為佢地出事嘅係同一條chromosome,咁啱係控制緊同一樣野

點解我地會分唔到就係好似條reddit link入面咁講
我地係唔擅於分辨唔係自己族/常見嘅人嘅樣
好似白人覺得亞洲人一樣樣,我地覺得佢地又係一樣樣咁
如果你細睇係會睇得出down syndrome patient佢地個樣唔同
但平時冇咩接觸嘅情況下,你每見一過都只會記得佢大概嘅面部輪廓
到你見到下一個嘅時候用腦入面嘅印象嚟對比就自然會覺得佢地係一樣樣
因為你只係留意到佢地嘅大致輪廓

快樂多過痛苦?
佢地有一堆neurological同physiological defects

你都識講佢地短命啲
就係因為佢地好多缺陷,根本長命唔到

點解果一條就咁大影響力?歸根究底只不過人類對異類外表辨識能力唔夠

btw,我感覺page1果條友未必真係想羞辱唐氏患者
純粹想表達係人類視覺上佢地等同其他物種

佢地係多咗一條染色體
即係多咗一堆基因
同埋有時一條基因嘅mutation已經可以決定個phenotype係點變
好似fruitfly嘅ubx gene咁
一mutate咗隻fruitfly會生多一對翼
老鼠嘅某啲Hox gene一異變就會搞到隻老鼠多或少咁幾節脊椎
所以唔係話一條基因嘅影響就唔大
Sickle cell anaemia都只係錯咗一個位base pair結果code錯amino acid,最後就係成個紅血球出事

thanks bro
但照計即使係conserved region也好, sequence among individuals都會唔同(呢樣野解釋到即使相同conserved region for a specific characteristics(phenotypic expression), 但容許有different traits of a character

所以我有一點唔明在於,即使down syndrome patient 出事全部在於extra 21 chromosome, 但每一條distinct chromosome 上既sequence都唔同,即使控制同一樣都好,都會好'唔同expression'

但點解你話因為咁岩,所以'好似'?
