問2のｑ’の式の分母に2かけてるのはどうしてですか

この日, もつことになる。 がαより引き継がれやすいと, 世代を重ねるごとに変動をしながら, Aの遺伝子頻 度が大きくなる傾向になると考えられる。 153 問1 BB の個体: 36% Bbの個体: 48% bbの個体: 16% 問2 0.29 問3 41個体 Key Point 自然選択が働くと、特定の遺伝子型の個体が取り除かれ,ハーディー・ワインベルグの法 則は成り立たない。 解説 問1 遺伝子Bの遺伝子頻度をか. 遺伝子の頻度をg (p+g=1) とすると,この集団に おける遺伝子型の頻度は次の式で求められる。な (pB+qb)²= p²BB+2pqBb+q²bb とは いる。 よって, 遺伝子型 BB の個体の割合は2=0.62=0.36, 遺伝子型 Bb の個体の割合は2pg=2×0.6×0.4=0.48, 遺伝子型 66 の個体の割合は4=0.4=0.16 となる。 問2bbの個体がすべて取り除かれた後の, 対立遺伝子の遺伝子頻度を′とすると. BBの個体の割合が 0.36, Bb の個体の割合が 0.48 であったので(sp+Mo 0.48 g′'= (0.36 +0.48) ×2 0.48 0.84×2 =0.285≒0.29 となる。 変化後の遺伝子頻度で自由交配が行われれば, ハーディー・ワインベルグの法則から次 世代における遺伝子頻度は変わらないので,bの遺伝子頻度は0.29である。 問3 対立遺伝子の遺伝子頻度が0.29 なので, bb が取り除かれた後の対立遺伝子Bの 遺伝子頻度かは、 al p'=1-0.29=0.71 st Bb の個体の割合は2pg′=2×0.71×0.29=0.4118 ≒ 0.41 総個体数が100個体であれば,B6の個体数は100×0.41=41)

なぜこのような図になるのでしょうか

解説 f'(a) f(a) 1 2 よって,f(a) は am で最小となり、最小値は, 1 2' f(a)=Sdr は,-1≦x≦1 において放物線 y=x2 と直線ひこなの 間にある部分の面積を表す. y=x2 -1 0 a1 48 YA y=x² - y=a² y=a2 -1 0 la IC これより,明らかに a≧1 のとき, a が増加すればf (a) も増加する. よって, f(a) を最小にするa は 0<a≦1 の範囲にある.
