Answer: (C) Near homozygous and produces offspring of its own kind. Answer: (C) Near homozygous and produces offspring of its own kind Solution: A true-breeding line, after continuous self-pollination, shows stable inheritance and expression of a trait for several generations, i.e., it is essentially homozygous and gives offspring identical to itself.
- A.One that is able to breed on its own
- B.Produced due to cross-pollination among unrelated plants
- C.Near homozygous and produces offspring of its own kind✓
- D.Always homozygous recessive in its genetic constitution
