In peories, two genes on the same chromosome determine flower color and leaf color. For flower color, blue (B) is dominant to pink (b), and for leaf color, white leaves (W) are dominant to green ( w ). A true breeding peony with blue flowers and white leaves is crossed with a peony that has pink flowers and green leaves. The phenotypes among the progeny are: 370 blue flowers and white leaves; 14 blue flowers and green leaves; 12 pink flowers and white leaves; and 363 pink flowers and green leaves. The frequency of recombination between these two genes is:
O 3%
O 12%
O 26%
O 50%
