Question

What is a true breeding line?

Answer 1

True breeding line:

1. True breeding lines in the case of plants are those plants that have been generated through repeated self-pollination.
2. These plants become homozygous for a particular trait.
3. This trait is then passed on to future generations if bred with another true-breeding plant.
4. Along with the useful traits some harmful traits also keep on accumulating resulting in inbreeding depression.
