Definition
Two organisms that are described as true-breeding for a trait, when crossed, will always produce offspring with exactly the same genotype as them for that trait. This means true-breeding organmisms are homozygous for the true-breeding trait, It is important to remember that this applies both dominant or recessive traits.
