Why were true-breeding pea plants important for mendel's experiments ?

last question for now :]Why were true-breeding pea plants important for mendel's experiments ?
Back during the time of Mendel, people didn't know how or why or the chances of different traits being passed on from generation to generation, but they knew it happened.





Mendel wanted to find out what traits were passed, why they were passed, and the chances of them being passed on.





True-breeding pea plants were important because he didn't want mixed results. He wanted clear cut alternate forms of traits (yellow vs green, round vs wrinkled, etc), he wanted controlled matings and reciprocal crosses (for control over parental influence), and he wanted pure breeding lines as well as a controlled environment.





He took into account everything that may have played a role in his experiment, and because of it, he was able to come up with the results that he did.Why were true-breeding pea plants important for mendel's experiments ?
Because all of the offspring would produce the same color type. Had they been heterozygous, it would've produced both white and purple flowers.
