Detailed explanation-1: -A true-breeding organism, sometimes also called a purebred (biology slang: pure line or true-breeding line), is an organism that always passes down certain phenotypic traits (i.e. physically expressed traits) to its offspring of many generations.
Detailed explanation-2: -True breeding lines in the case of plants are those plants that have been generated through repeated self-pollination. These plants become homozygous for a particular trait. This trait is then passed on to future generations if bred with another true-breeding plant.
Detailed explanation-3: -Definition. True breeding lines are the plants that produce only offspring of the same characteristics on self pollination. Characteristic features. Characteristic features of a true-breeding line are as follows: Plants should be homozygous for a trait, with both dominant or both recessive alleles.
