Practice question
Question
A To transgenic plant contains two unlinked copies of the T- DNA of which one is functional and the other is silenced . Segregation of the transgenic to non transgenic phenotype would occur in a (i) Ratio in progeny obtained by backcrossing and in a (ii) ration in F1 progeny obtained by self pollination. Fill in the blanks with the correct combination of (i) and (ii) from the options given below:
Explanation
a to transgenic plant contains two unlinked operates via (i)— 1:1 and (ii) -- 3 : I represents established outcome. functional assays validates option B. Other options propose substrate or regulatory direction, inconsistent with published kinetics and mutant phenotypes.
