| If an organism has 2 different alleles for a trait we call that individual a | hybrid (or we say heterozygous) |
| What does TT mean? | Two capital letters means 2 DOMINANT alleles |
| What does Tt mean? | One dominant allele and one recessive allele |
| What does a Punnett Square show? | The possible outcomes of a genetic cross |
| What is a phenotype? | An organisms physical appearance. (In other words....it is what we can see) |
| What does CODOMINANCE mean? | Neither allele is dominant. They both show up. |
| What do we call different forms of a gene? | ALLELES |
| What is a genotype? | Its actual genetic make-up. (It's 2 letters) |
| If an organism has 2 identical alleles for a trait we call it | Homozygous or purebred |
| What is a pedigree chart used for? | Tracking a particular trait through multiple generations of a family |

| What does a blackened circle represent? | A female who has the trait |
| What does a blackened square represent? | A male who has the trait |
