Mendel conducted artificial hybridization/cross pollination using true breeding pea
lines. True breeding lines are those that undergo continuous self-pollination and
shows stable trait inheritance.
Hybridization experiment includes emasculation (removal of anther) and transfer of
pollen (pollination).
