n tomato plants, tall vine (D) is dominant over dwarf vine (d) and round fruit (O) is dominant over oval-shaped fruit (o). Two tall, round-fruit shape plants (plants 1 and 2) are crossed with dwarf, oval-shape fruit plants. The results are as follows: i) Why is there a difference in the proportionate number of plants in each phenotypic class of the offspring resulting from test crosses of plants 1 and 2? (ii) Calculate the recombination frequency between the genes D/d and O/o in tomatoes. (iii) Draw a chromosome map for these genes. (Use underscore (_) to draw the line for the map)
