Can anyone help me with this question? I am very confused!
In corn-
coloured kernal – R
colurless – r
green plant colour – Y
yellow plant colour – y

The R and Y genes are linked. Two different plants (1 and 2) that were heterozygous for each trait – RrYy – were test crossed to plants that were homozygous for reccessive alleles. this info was gotton from that:
Coloured green -plant 1 145 plant 2- 18
colured yellow – 1-13 2-175
colourless green – 1 – 17 2- 185
colourless yellow – 1- 125 2- 22

what phenotypic ratio is expected in each if the genes were unlinked
and
plant 1 and 2 were generated by crossing true breeding plants. Crossing RRYYx rryy plants generated plant 1. The parents of plant 2 had genotypes that were different from the genotypes of the parents of plant 1. What are the genotypes of parents from plant 1?

Very confusing question. Any help is much appreciated.
