Bio: 臉上的"酒窩"同基因遺傳其實有冇關係?

2076

我聽人講過"耳珠"係同基因有關
突然諗到自己臉上o個粒唔起眼既"酒窩"
咁我想問下"酒窩"又同基因有無關係呢?

如果係, 咁係Discontinuous定continuous variation呢?

另外Discontinuous同Continuous variation既分別
係咪在於有幾多遺傳物質控制o個樣特徵?
即係不連續->少D基因控制
連續->好多基因控制

希望大家可以解答...

而家CE都要continuous
anyway, 酒粒個問題我答唔到你, 我都唔識
至於點解會有continuous variation係因為polygenic, 有好多條gene控制呢個chacter (應該係咁)
另外應該會normal distribution

不過成個genetics我最唔熟就係呢度... 我覺得好難

仲加左D Evolution, Genetic Engineering
都唔知乜來的, past paper又無

使唔使借我既AL notes俾你

咁又唔使, AL太高層次了, CE好少
本textbook呢兩課加埋得十版左右

不過真係唔知點溫, 想放棄呢兩課,
專攻Repoduction, Transport呢d必出topic

酒粒只是 muscles of facial expression 的 defect 做成...... 簡單講, 係 muscle 差少少相連先有

剩係個頭 D muscle 都十幾舊..... 唔至 continuous/discontinuous 可以解釋 wor.... 剩係兩塊 muscle 個位都唔知道係點控制啦.... CE, 講 discontinuous 啦.

唔連好過連

只要唔係normal distribution就唔係continuous?

同基因遺傳有關
我問過讀h.bio的同學了

人有九成九 variation 都同 genes 有關 ga la

我文科的

應該係遺存基因有關, 但我細個都有, 但人大左變左無。
