| Question | Answer |
| Biology of Propagation | Goal: to maintain unique characteristics of plants (preserve genotypes) |
| Genotype | Genetic makeup of plant (gene controlled) |
| PP or pp | Homozygous (Two of the same) |
| Pp | Heterozygous (One dominant and one recessive) |
| Phenotype | Appearance of plant Genotype + environmental factors (Appearance changes with location) |
| Meiosis | Sexual reproduction |
| Sexual reproduction | Through seeds |
| Formula for Meiosis | N + N = 2N |
| N + N = 2N | Male + female = Zygote Pollen + Egg = seeds Stamen(anther) + Pistil (ovary) |
| Homozygous | Similar traits coming from both male and female (Offspring resemble parents) (True to type) |
| Heterozygous | Offspring will differ from parents and each other |
| Natural seedling selection | Occurs often and leads to natural selection of better plants (Need man to keep from dying off) |
| Mitosis | Asexual reproduction |
| Asexual reproduction | Through cutting/division Vegetative or Sporophytic Each cell can produce a daughter Are identical in traits |
| Daughter cell | Identical offspring |
| Area of occurence | Shoot apex Root apex Vascular cambium Intercalary zone Callus tissue |
| Adventitious | New growth points on established structures |
| Adventitious roots | A root growing from a location other than underground |
| Adventitious shoots arise at: | root nodes Iter-nodeally on stems Leaf edges Dormant buds |
| Watersprouts | New shoots from dormant buds (Clones) |
| Every node | Has a dormant bud |
| Watersprouts can | Occur from damage or stress |
| Cultivar | Plants reproduced vegetative (asexual) from a particular species with unique characteristics (Homo) |
| "Plant name" | Cultivar |
| Plant patents | 1930s Last 17 years Can reapply 1x You must prove it can survive Can not be found in nature |
| PT on plant tag | Means patented |
| You can't patent | Tuberous plants or things growing naturally in nature |
| Plant Variety Protection | 1970 Property protection for breeders of new varieties of seeds and tubers No renew (F1 hybrid seeds: cotton, alfalfa, soybean) |
| Trademarks | Lasts 10 years Can be renewed indefinitely as long as it remains in constant use Offers protection of a name |
| Oldest trademark | Rose, 1907 |
