生物、連鎖と組み換えの問題です。(2)が両方とも解説を読んでも分からないので教えてください。 ①の方はAB:abの分離比が3:1になるところまではわかるのですが、Ab:aBが0:0になるところがわからないです。②は青のマーカーが引いてある箇所のAB:Ab:aB:ab=4:1... Read More

連鎖と組換え(1) 次の問いに答えよ。 (1) ある植物では,花色の遺伝子と種子の形の遺伝子は同一染色体上にあり,花色の 赤 (A) は白(a)に対し, 種子の形の丸 (B) はしわ (b)に対し, 顕性である。 ① 花が赤く,種子が丸い個体Xに潜性ホモ接合の個体を交配したところ,そ の子に赤丸: 赤・しわ:白・丸:白 しわが 10:33:10 の比で出現した。 個体Xの遺伝子型を決定せよ。 ② A, B両遺伝子間の組換え価を小数第1位まで求めよ。 ③ A. B遺伝子間に①と同様な比で組換えが起こる個体Xを自家受粉させ,次 世代を育てた場合,どのような表現型の個体がどのような比で出現するか。 (2) ある動物において, 遺伝子AとBは連鎖の関係にあり,またaとbはそれぞれA とBの潜性対立遺伝子とする。 次の条件1および2のもとで, F (AaBb) どう しの交配で生じた F2 の表現型 ( [AB] [Ab]:[aB] [ab]) の分離比を答えよ。 ①① 〔条件1] 雌雄ともに遺伝子AとBは連鎖 ② 〔条件2] 遺伝子AとBの組換え価が雌では20%, 雄では0% (愛知教育大)
