| Alleles | different forms of a gene |
| Dominant | An allele that is expressed whenever it is present. Dominant alleles are represented by a capital letter. Ex: HH or Hh |
| Homozygous | having two of the same allele for a trait Ex: BB or bb |
| Heterozygous | having two different alleles for a trait Ex: Rr |
| Mutation | a change in genetic information |
| messenger RNA (mRNA) |
a molecule that carries information from genes to the site of protein synthesis in the cell

M Rna (binary/octet-stream)
|
| Amino acids | the building blocks of proteins |
| Harmful mutation | a change in genetic information that causes a disease, disorder, or other negative impact |
| Beneficial mutation | a change in genetic information that helps a living thing survive in its environment |
| Neutral mutation | a change in genetic information that does not affect an organism |
| Recessive | An allele that is expressed when a dominant allele is not present. Recessive alleles are represented by lower case letters. Ex: rr |
| Punnett Square | A diagram used to show the genotypes two individuals can produce when crossed. |
