In tomato plants, three genes are linked on the same chromosome. Tall is dominant to short, skin that is smooth is dominant to skin that is peachy (fuzzy), and fruit with a (wild-type) round tomato shape is dominant to fruit with an oblate (flattened) shape. A plant that is true-breeding for dominant traits was crossed to a short plant with peachy skin and oblate fruit. The F1 plants were then testcrossed to short plants with peachy skin and oblate fruit. The following results were obtained for the F2 offspring. 151 tall, smooth, normal 33 tall, smooth, oblate 11 tall, peachy, oblate 2 tall, peachy, round 155 short, peachy, oblate 29 short, peachy, round 12 short, smooth, round O short, smooth, oblate Construct a genetic map that shows the order of these three genes and the map distances between them. Also, could you please make a simple three factor cross representation so that I could understand it.
Q. In tomato plants, three genes are linked on the same chromosome. Tall is dominant to short, skin that is smooth is dominant to skin that is peachy (fuzzy), and fruit with a (wild-type) round tomato shape is dominant to fruit with an oblate (flattened) shape. A plant that is true-breeding for dominant traits was crossed to a short plant with peachy skin and oblate fruit. The F1 plants were then testcrossed to short plants with peachy skin and oblate fruit. The following results were obtained for the F2 offspring.
151 tall, smooth, normal
33 tall, smooth, oblate
11 tall, peachy, oblate
2 tall, peachy, round
155 short, peachy, oblate
29 short, peachy, round
12 short, smooth, round
O short, smooth, oblate
Construct a genetic map that shows the order of these three genes and the map distances between them.
Also, could you please make a simple three factor cross representation so that I could understand it.
