Detailed explanation-1: -Plants that undergo self-fertilisation for several generations, such that their traits under consideration remain unchanged are known as true-breeding or pure breeding plants. It is one that when self-pollinated, produces offspring with the same traits.
Detailed explanation-2: -An example of true breeding is that of the Aberdeen Angus cattle. The cattle have been black for many generations, which is an indication that such trait passed on from many generations remains pure. Another example is the mating between two dogs of the same breed.
Detailed explanation-3: -In the animal world, true-breeding organisms are also referred to as purebred. Purebred organisms are often highly valued because they are guaranteed to display the traits normally associated with their breed and will pass them down to any offspring.
Detailed explanation-4: -Updated on August 20, 2019. A true-breeding plant is one that, when self-fertilized, only produces offspring with the same traits. True-breeding organisms are genetically identical and have identical alleles for specified traits. The alleles for these type of organisms are homozygous.
