प्रश्न
What is meant by true-breeding or pure breeding lines/strain?
उत्तर
A true-breeding line (Pure-breeding strains) means it has undergone continuous self-pollination having stable trait inheritance from parent to offspring. Matings within pure breeding lines produce offsprings having specific parental traits that are constant in inheritance and expression for many generations. Pure line breed refers to homozygosity only.
