A plant whose offspring share the same traits as the parent

A plant whose offspring is genetically different from the parent.

Detailed explanation-1: -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.
Detailed explanation-2: -With plants, true breeding occurs when plants produce only offspring of the same variety when they self-pollinate. For instance, a plant that has blue flowers will produce only seeds that will grow into plants that have blue flowers. With true breeding, the trait is passed on to all subsequent generations.
Detailed explanation-3: -Answer and Explanation: The offspring of true breeding parents are called the F1 generation. If members of the F1 generation were to be interbred their offspring would be the F2 generation.
Detailed explanation-4: -Hint: A true-breeding plant is one that when self-fertilized produces offspring with same traits. True-breeding organisms are genetically identical. They also have identical alleles for specific traits. The alleles are homozygous.
Detailed explanation-5: -Two organisms that are described as true-breeding for a trait, when crossed, will always produce offspring with the same genotype as them for that trait. This means true-breeding organisms are homozygous for the true-breeding trait, It is important to remember that this applies both dominant or recessive traits.
