Question

In tomatoes, round fruit (R) is dominant over long fruit (r), and smooth skin (S) is dominant over fuzzy skin (s). A true-breeding round, smooth tomato (RRSS) was crossed with a true-breeding long, fuzzy tomato (rrss). All the F1 offspring were round and smooth (RsRs). When these F1 plants were bred there were 43 round smooth offspring and 13 long, fuzzy offspring. Are these two genes likely to be on the same chromosome? Explain.

Answer 1

Answer:

Round, smooth: 43      

Long, fuzzy: 13
