In tomatoes, tall is dominant to dwarf, and smooth fruits are dominant to hairy fruits. A plant homozygous for both dominant traits is crossed with a plant homozygous for both recessive traits. The F1 progeny are test-crossed with the following results in the F2 progeny: 96 tall with smooth fruits; 94 dwarf with hairy fruits; 6 tall with hairy fruits; and 4 dwarf with smooth fruits. These data indicate that the genes areA. linked, and show 20 percent recombination. B. linked, and show 10 percent recombination. C. on different chromosomes. D. linked, and show 5 percent recombination. E. linked, and show 40 percent recombination
