Question

The model plant neitzelweed (Bogus testplantii) normally has large, blue fruit and spiny stems. Recessive mutants have been found with white, small fruits and spineless stems. A pure breeding wild type plant is crossed with a pure breeding white, small, spineless plant. All of the F1 are wild type phenotype. When the F1 is crossed with the homozygous recessive parent the progeny types and numbers below are observed. Create a genetic map showing the relationship and distances between the genes for these three traits.

54 blue large spiny​​60 white small spineless

4 blue small spineless​​6 white large spiny

12 blue, small spiny​​16 white large spineless

21 blue large spineless​27 white small spiny
