In pea plants, round pea texture is dominant over wrinkled texture. How can you obtain true-breeding pea plants having round peas with the least amount of work? ​

Accepted Answer

A) Cross plants having round peas with plants having wrinkled peas. Select round pea plants from the progeny because they are now true-breeding.
