| Homozygous; | characteristics of having two of the same alleles at the same locus of sister chromatids. |
| Heterozygous | characteristics of having two different alleles that appear at the same locus of sister chromatids. |

| Mutation | change in the DNA sequence. |
| Autosome(s); | chromosome that contains genes for characteristics not directly related to the sex of an organism. |

| Deoxyribonucleic Acid (DNA); | molecule that stores genetic information in all organisms. |
| Ribonucleic Acid (RNA); | nucleic acid molecule that allows for the transmission of genetic information and protein synthesis. |
| Replication; | process by which DNA is copied. |
