You want to develop a line of sunflowers that stand exactly 4 feet tall so they can block an unsightly fence in your yard. In doing so, you isolate two pure-breeding lines. One has a genotype A1A1B1B1C1C1 and is 6 ft tall, whereas the other has the genotype A2A2B2B2C2C2 and is only 3 ft tall. In the previous question, you determined the height of the F1 plants. When you cross these two heterozygous plants together, what proportion of the F2 generation would give you the 4 ft height that you are hoping for?
