A cross was made between a Red and Long flowered (RRLL) plant and a blue and dwarf flowered (rrll) plant. The resulting F1 plants were testcrossed to blue and dwarf plants. 140 red and long 28 red and dwarf 32 blue and long 145 blue and dwarf After showing your Punnett square for the testcross, use the Chi Square test to determine if the genes are assorting independently. If they are linked, calculate the distance between the two genes. Show your work.
