14 In the garden pea, orange pods (orp) are recessive to green pods (Orp), and sensitivity to pea mosaic virus (mo) is recessive to resistance to the virus (Mo). A plant with orange pods and sensitivity to the virus was crossed to a truebreeding plant with green pods and resistance to the virus. The F1 plants were then testcrossed to plants with orange pods and sensitivity to the virus. The following results were obtained: 145 orange pods, virus-sensitive 150 green pods, virus-resistant 21 orange pods, virus-resistant 24 green pods, virus-sensitive The map distance between the two genes is .... map unit (3 Points) Select your answer 22.83 13.24 20.24 10.94 ? 13.75 8.33
