3. In maize, green (G) colour plant is dominant over yellow ( \( \mathrm{g} \) ), full (R) seed is dominant over shrunken(r) seed and coloured (C) grain is dominant over colourless (c). From the three point test cross data given below, determine the order of the genes, estimate the map distance between them, construct their linkage map, calculate the coefficient of coincidence and coefficient of interference.
\begin{tabular}{|c|c|c|c|c|c|}
\hline GCR & & 22 & \( \mathrm{gcR} \) & - & 0 \\
\hline \( \mathrm{gCr} \) & - & 23 & \( \mathrm{GCr} \) & - & 5 \\
\hline \( \mathrm{gCR} \) & - & 390 & \( \mathrm{gCr} \) & - & 5 \\
\hline \( \mathrm{Gcr} \) & - & 365 & \( \mathrm{GcR} \) & - & 59 \\
