なぜRの遺伝子頻度の求める計算で分母の数を✖️2してるか分かりません。教えてください。

手順 STEP 4 と同じ記号を使っ 男性の中で赤緑色覚異常が1% (=0.01) なので, 228 g=a p=1-a=b 女性保因者は XX' という遺伝子型なので, その比率は 2pg である。 よって女性 (これを100%とする) の中での保因者の 頻度は,2×a×b=c となり, %で表すと dとなる。 STEPS 遺伝子頻度が変化する場合をマスターしよう (1) ある植物で種子の形について丸 (RR と Rr) が 84%, しわ (rr) が 16% を占 める集団があるとしましょう。 R, r の遺伝子頻度をそれぞれp, g(p+g=1) とすると, ∴.p=1-0.4=0.6 RR: Rr: rr = p2: 2pgg' から、g2=0.16 g =0.4 となり,ハーディ・ワインベルグの法則が成り立てば、この遺伝子頻度は代 を重ねても変化しません。 (2)では,この集団からしわの個体をすべて除いて, 丸の集団の中で自由に交 配させると,次世代の集団の遺伝子頻度はどうなるでしょうか? p = 0.6g = 0.4 なので、 残った集団は, この集団での遺伝子頻度を求めます。 RR: Rr = p2 : 2pg=0.62 : 2×0.6×0.4=0.36 : 0.48=3:4 Rの遺伝子頻度は, f 2 四 3×2 +4×1 5 ( 3 +4)×2 7' よって, R:r=52 これが自由に交配するので、次の世代は, = 5R 2r 25RR 10Rr 4rr 5R 2r 10Rr a : 0.01 b: 0.99 rの遺伝子頻度は, c: 0.0198 d: 1.98% RR: Rr: rr = 25:20:4 よって, この新しい世代の集団でのR遺伝子の頻度は, 25 ×2 +20×1 (25+20+4) × 2 =0.714・・・0.71- 4×1 2 14 7 - もとは 0.6 だったのに
