A cross between cucumbers with tuberculate fruit (Tu) and dull fruit skin (D), both of which are dominant traits, and cucumbers with normal fruit shape (tu) and skin (d) produces an F1 of cucumbers that all have tuberculate fruit with dull fruit skin. When these F1 cucumbers are crossed with cucumbers that have normal fruit shape and skin, they produce these offspring: tuberculate fruit and dull fruit skin: 210 tuberculate fruit and normal fruit skin: 34 normal fruit shape and dull fruit skin: 40 normal fruit shape and skin: 216 total: 500 What is the map distance between the Tu and D loci?
