Round is the dominant trait for a pea; the recessive allele produces a wrinkled pea. How can you
obtain true-breeding pea plants having round peas with the least amount of work?
a. Cross plants having round peas with plants having wrinkled peas. Select round pea plants from the progeny because they are now true-breeding. b. Cross plants having round peas with other plants having round peas. Do this for multiple generations. c. Cross plants having round peas with plants having wrinkled peas. Select round pea plants from the progeny and do a test cross to determine which parental plants were homozygous dominant. Use these homozygous pea plants as your true-breeding plants. d. Cross plants having round peas with plants having wrinkled peas. This will tell you which round pea plants are homozygous dominant and are thus true-breeding. e. It's not possible. You can only get true-breeding plants that have wrinkled peas.
