DSE 生物BIOLOGY 區

如果同survival fitness冇關，咁我想知你仲可以點解釋

我都係答呢個

james fong未出答案

本身條gene 可以randomly located at dominant 或者recessive allele
只係dominant allele 會被eliminate
但individual with recessive allele 唔會受影響，照樣可以pass 到條allele比下一代
所以最終先會見到好多disease 都常見於recessive allele

開始chem同最尾bio都衰左

等mc ans

d elective炒晒可以點
已經係retaker

考bio我覺得我去左吹水大會

臨收卷醒起essay搞錯左一個keyword可能半題無分，點都好考完唔理，thanks答過我問題既巴打

有冇Mc questions

Hkcc

衰chem衰bio 衰頭衰尾 唉

有冇人可以影份mc黎睇下

我都係，兩份paper 1都前面做得太慢，唔夠時間，搞到後面做得太快，錯好多Careless

得中文要唔要?

都好啊

好

我mc應該錯好多😭😭 大家唔好介意

用中文考唔係仲難咩

上面巴打擺咗,咁我擺唔擺好

我都係靠9up 唔多知marking想問乜
特別e2

Explain why genetic diseases are often carried by recessive allele

By comparing the effects of the two breeding processes on the genetic composition in the offspring
唔識答
第2個係答homologous and heterozygous 既分別？

但時間好少唔點夠寫
e3仲要有成3版
