バーディーワインベルグの法則 (p+q)^2の意味がわかりません

第3節 進化のしくみ 目標 ①進化と遺伝子との関係や、 進化の要因について理 ②新たな種類の生物が生じる過程について理解する。 1 進化のしくみ ?進化を遺伝子の視点からとらえると,そのしくみはどのように説明できるだろうか。 A 進化と遺伝子頻度 いでんし gene pool ある 伝子座の遺伝子プールは、 すべての個体がもつ全アレルで構成される。遺伝子プー 交配可能な個体からなる集団中の遺伝子全体は, 遺伝子プールと呼ばれる。 において、1つの遺伝子座のアレルの頻度 (割合) を遺伝子頻度という(図3)。 集団 遺伝子プール でんしひんど gene frequency この集団の場合, 代を経ても せず,集 は遺伝子 る。 この ディー Hardy-Wein という Q a a a a AA: Aa:aa=3:2:5 Aの遺伝子頻度 遺伝子 A の数 E 800 20 = 0.4 遺伝子Aとaの総数 a aの遺伝子頻度 遺伝子 aの数 12 20 遺伝子Aとa の総数 = 0.6. a a 図37 遺伝子頻度 MOVIE ある生物の集団中にある遺伝子のなかから、1組のアレルAとaに着目し,それぞ れの頻度をpおよびq とする(p+q=1)。 この集団を構成する個体の遺伝子型には、 AA, Aa, aaの3種類があり,これらが自由に交配した結果生じる子の世代の各遺 表2 遺伝子型とその頻度 伝子型とその頻度は,次のようになる(表2)。 (p+g)2= 2pq p2 + + q² A (p) a (q) (AAの頻度) (Aaの頻度) (aaの頻度) 子の世代の遺伝子Aの頻度は,次のようになる。 A (p) AA (2) Aa (pq) a(g) Aa (pq) aa(q^) Aの遺伝子頻度: 2×(AAの頻度)+(Aaの頻度 ) (遺伝子Aとaの頻度) 2p2+2pq 2p(p+g) = = =p 2p2+4pq+2q22(p+q)2 また,遺伝子aの頻度は,次のようになる。 aの遺伝子頻度: (Aaの頻度) +2 × (aaの頻度) (遺伝子Aとaの頻度) 42 第1章 生物の進化 2p2+4pq+2q22(p+q)2 以上から、子の世代のAとaの遺伝子頻度は, 親世代と変わらないことがわか = 2pq+2q2 2g(p+9)
