In maize coloured (C) and full endosperm (F) is dominant over colourless (c) and shrunken endosperm (f). \(F_1\) generation was subjected to test cross. It produced four phenotypes in the following percentages:
\[
\begin{aligned}
&\text{Coloured full }=48\%
&\text{Coloured shrunken }=5\%
&\text{Colourless full }=7\%
&\text{Colourless shrunken }=40\%
\end{aligned}

Find out the distance between two non-allelic genes.
Show Hint
Gene distance is calculated as
\[
\boxed{
\text{Map distance (cM)}
=
\%\text{ recombinants}.
}
\]
Here,
\[
5\%+7\%=12\%.
