1. a section of DNA on a chromosome that has genetic information for one trait.
4. the process that occurs when pollen grains land on a female reproductive structure of a plant that is the same species as the pollen grains.
5. a type of asexual reproduction that occurs when an offspring grows from a piece of its parent.
6. a model that shows genetic traits that were inherited by members of a family.
11. a genetic factor that is blocked by the presence of a dominant factor.
13. the way an organism reacts to other organisms or to its environment.
15. a genetic factor that blocks another genetic factor.
17. how a trait appears or is expressed
18. a form of asexual reproduction where an organism grows on the body of its parent.
20. the study of how traits are passed from parents to offspring.

1. the alleles of all the genes on an organism’s chromosomes; controls an organism's phenotype.
2. the growth of a plant toward or away from light.
3. a genotype in which the two alleles of a gene are different.
7. the response of a plant to touch.
8. a different form of a gene.
9. reproduction type of reproduction where the genetic material from two different cells combine, producing an offspring.
10. the passing of traits from parents to offspring.
12. the response of a plant to gravity.
14. a genotype in which the two alleles of a gene are the same.
16. reproduction a type of reproduction in which only one parent organism or part of that organism produces a new organism.
19. reproduction a form of asexual reproduction in which offspring grow from a part of a parent plant.
