If a plant is test-crossed which of the following genes are linked? A. Flower color and height B. Flower color and flower placement C. Flower placement and height D. None of these genes appear to be linked phenotype Tall/purple/axial Tall/white/axial Short/ ur Short/white/axial Short/white/terminal Short/purple/terminal Tall/white/terminal Tall/purple/terminal Progeny number 3709 70 2034 2507 39 72 3507 Solution The linked in a cross table is observable by parent genotypes. The parental genotypes are always those who are in maximum numbers. The parental are Tall/ purple / axial and Tall purple terminal are dominant [high number]. Short/ white/ terminal and short white axial are recessive parents [less number] As we can see in both parents only axial and terminal are change, other two characters height and flower color are not changing. Therefore, they are tightly arrange and called as linked. The option A is correct..
