In corn, the genes v (virescent seedlings), pr (red aleurone) and bm (brown midrib) are all on chromosome 5, but not necessarily in the order given. The cross:

v+ pr bm / v pr+ bm+ X v pr bm / v pr bm

Produces 1000 progeny with the following phenotypes:

Red - brown 209
Virescent 213
Red 175
Virescent - brown 181
Brown 69
Virescent - red 76
Wild type 36
Virescent - red - brown 41

a. Determine the gene order, and the recombinant frequencies between adjacent genes.

b. Determine the coefficient of coincidence and the level of interference. What do theses two terms mean?
