In tomato plants, tallness is dominant over dwarfness and hairy stems are dominant over hairless stems. True-breeding (homozygous) plants that are tall and have hairy stems are available. True-breeding (homozygous) plants that are dwarf and have hairless stems are also available. Design an experiment to determine whether the genes for height and hairinessof the stem are on the same or different chromosomes. Explain how you will be able to determine from the results whether the genes are on the same or different chromosomes.
True-breeding with tomato plants homework question--PLEASE HELP ME! IM SO LOST!?
You have two dominant traits and two recessive traits. If they were on separate chromosomes, you would expect a homozygous recessive bred with a dihybrid to produce equal proportions of phenotypes. If they're on the same chromosome (and not too far apart on that chromosome), the proportions will be very different.
A good explanation can be found in the link.
