purebred | Is a organism that is the offspring of many generations that have th same trait. |
gene | Is the word scientists use to name the factors that control a trait. |
allele | Are different forms of a gene. |
dominant allele | Is one whose trait always shows up in the organism when the allele is present. |
recessive allele | Is hidden whenever the dominant allele is present. |
