True Breeding Varieties: Definition, Characteristics, and Uses

True breeding varieties, also known as purebred or homozygous varieties, are plants or animals that, when self-fertilized or bred with other individuals of the same variety, consistently produce offspring with the same traits as the parents. This means that the offspring will have identical traits to the parent plant or animal, generation after generation. True breeding varieties are often used in breeding programs to maintain specific traits in a population.
