In the tomatoes of Problem, an F 1 offspring ( RrSs ) was mated with a homozygous recessive ( rrss ). The following offspring were obtained: 
What is the most likely explanation for this distribution of phenotypes?
Problem
In tomatoes, round fruit ( R ) is dominant to long fruit ( r ), and smooth skin ( S ) is dominant to fuzzy skin ( s ). A true-breeding round, smooth tomato ( RRSS ) was crossbred with a true-breeding long, fuzzy tomato ( rrss ).
All the F 1 offspring were round and smooth ( RrSs ). When these F 1 plants were bred, the following F 2 generation was obtained:
Round, smooth: 43
Long, fuzzy: 13
Are the genes for skin texture and fruit shape likely to be on the same chromosome or on different chromosomes? Explain your answer.
