- Bself-pollination
- Ctissue culture
- Dnegative propagation
Explanation
Whether a tall plant is homozygous (TT) or heterozygous (Tt) can be verified by self-pollination: if the progeny include any short (tt) plants, the parent was heterozygous; if all progeny are tall, it was homozygous. Cross-pollination with an unknown partner would not resolve the genotype, and tissue culture merely clones the plant. The method is self-pollination.
