According to the figure- in the first generation- 150 hybrid dsDNA are produced- In second generation -xA0-150-xA0-hybrid dsDNA and 150 normal dsDNA are produced- in ratio 1-1-So- the correct answer is -quot-150 hybrid and 10 normal dsDNA are produced-quot-

According to the figure, in the first generation, 150 hybrid dsDNA are produced. In second generation 150 hybrid dsDNA and 150 normal dsDNA are produced. in ratio 1:1.
So, the correct answer is "150 hybrid and 10 normal dsDNA are produced".
