In maize, colored endosperm $\left(\mathrm{C}\right)$ is dominant over colourless $\left(\mathrm{c}\right)$ ; and full endosperm $\left(\mathrm{R}\right)$ is dominant over shrunken $\left(\mathrm{r}\right)$. When a dihybrid of ${\mathrm{F}}_1$ generation was test crossed, it produced four phenotypes in the following percentage:
Coloured full - $48\%$
Coloured shrunken - $5\%$
Colourless full - $7\%$
Colourless shrunken - $40\%$
From this data, what will be the distance between two non-allelic genes?
