A true-breeding plant is one that:
A
Produced due to cross-pollination among unrelated plants.
B
Near homozygous and produces offspring of its own kind.
C
Always homozygous recessive.
D
Is a hybrid produced by crossing two different species.
Explanation
A true-breeding line is one that, having undergone continuous self-pollination, shows stable trait inheritance and expression for several generations. It is homozygous (e.g., TT or tt). If it were heterozygous (Tt), it would segregate in the next generation, failing to produce offspring of its own kind.
