Question

You are mapping chromosomes in tomatoes.The gene for oblong vs round fruit is located 35 centimorgans from the gene for lacy vs round leaves.The gene for axial vs terminal flowers is located 25 centimorgans from the gene for oblong vs round fruit.However, when you backcross to map the genes for leaf shape and flower location, you get a 1:1:1:1 ratio for the different recombinant and parental phenotypes.What do you now know about these genes?
Answer
A.
The genes for leaf shape and flower location are on the same chromosome and located 50 centimorgans apart.
B.
The genes for leaf shape and flower location are on different chromosomes.
C.
The genes for leaf shape and flower location are on the same chromosome and located 60 centimorgans apart.
D.
Because they are assorting independently, you don't actually know whether the genes for leaf shape and flower
