A true breeding plant is
one that is able to breed on its own
produced due to cross-pollination among unrelated plants
near homozygous and produces offspring of its own kind
always homozygous recessive in its genetic constitution
True breeding plants are nearly homozygous and produce offspring of their own kind. True breeding lines are those plants that have been generated through repeated self - pollination and have become homozygous for a particular trait. This trait is then passed onto the future generations if bred with another true-breeding plant.
Hence, the correct answer is 'near homozygous and produces offspring of its own kind.'
