| 1.traits | charachteristics |
| 2.genes | a small piece of the DNA that controls the traits of an organism |
| 3.DNA | the chemical code held by chromosomes that tells the cells what to do |
| 4.heredity | passing of traits from parents to offspring |
| 5.genetics | the study of how traits are inherited |
| 6.purebred plants | an organism that is the offspring of parents having the same genetic makeup |
| 7.hybrids | plant produced by crossing purebred plants that each have a different form of the same trait |
| 8.dominant gene | a gene that will always be expressed if it is present in a person’s chromosomes |
| 9.recessive gene | the gene that is hidden when a dominant gene is present |
| 10.phenotype | the physical appearance of an organism |
| 11.genotype | the genetic makeup of an organism |
| 12. incomplete dominance | the blending of genes together instead of one being dominant while the other is recessive |
| 13.codominance | the expression of both genes instead of one having recessive while the other is dominant |
| 14.pedigree | a chart that traces a particular trait through many generations |
| 15.sex | linked traits |
