| Question | Answer |
|---|---|
| Gene | segment of DNA that codes for a trait |
| Allele | different versions of a gene (ex. A or a) |
| Trait | a characteristic (hair/eye color) |
| Dominant | allele that masks another (B) |
| Recessive | allele that is masked (b) |
| Genotype | genetic makeup (Aa, BB, cc) |
| Phenotype | physical appearance (brown eyes) |
| Homozygous | two same alleles (BB or bb) |
| Heterozygous | two different alleles (Bb) |
| Carrier | heterozygous for a recessive trait (has it, doesn’t show it) |
| Complete Dominance | Dominant completely masks recessive |
| Incomplete Dominance | heterozygous is a blend (ex. Red = R White = W Pink = RW |
| Codominance | both alleles are expressed (ex. AB blood type) |
