Theo bài và theo NTBS ta có: \(\left\{{}\begin{matrix}A=T=20\%N=600\left(nu\right)\\G=X=30\%N=900\left(nu\right)\end{matrix}\right.\)
\(a,\) \(L=\dfrac{N}{2}.3,4=5100\left(\overset{o}{A}\right)\)
\(b,H=N+G=3900(lk)\)
\(c,\) \(A_1=T_2=250\left(nu\right)\) \(\rightarrow A_2=T_1=A-A_1=350\left(nu\right)\)
\(G_1=X_2=300\left(nu\right)\) \(\rightarrow G_2=X_1=G-G_1=600\left(nu\right)\)
\(d,\) Do mạch 2 của gen là mạch khuân nên ta có:
\(\left\{{}\begin{matrix}rA=T_2=250\left(nu\right)\\rU=A_2=350\left(nu\right)\\rX=G_2=600\left(nu\right)\\rG=X_2=300\left(nu\right)\end{matrix}\right.\)
