Lesson Transcript
Instructor: Jeremy Battista
True breeding plants were utilized by Gregor Mendel during his experiments with pea plants. We will look into detail here as to how useful these were in determining inheritance.

Gregor Mendel & Inheritance Experiments.

Gregor Mendel was a monk whose work in the field of genetics has earned him the moniker 'Father of Modern Genetics.' It wasn't until after his death, though, that many of his ideas and writings came out in the scientific field.

Mendel's experiments with true breeding pea plants led us to a deeper understanding of how and why parents pass on specific traits to their offspring. Mendel used true breeding pea plants for a certain trait. He would then cross them and see what the resulting offspring looked like. He found that the resulting offspring ALWAYS looked like just one of the parents, not a combination of the two. He was able to ascertain that this would always occur in the F1 generation of offspring for any true breeding parental generation (P) for any specific trait.

True Breeding: What's It Mean?

True breeding means that the parents will also pass down a specific phenotypic trait to their offspring. Remember that a phenotype is the outward appearance of something. True bred organisms will have a pure genotype (genetic expression of a trait) and will only produce a certain phenotype. True bred is sometimes also called pure bred.
