Allele | One member in a pair gene pair that controls characteristics, such as eye color or hair color. |
Chromosome | A threadlike structure of nucleic acids and protein that carries genetic information in the form of genes. |
DNA | Deoxyribonucleic acid, makes up chromosomes and the carries genetic information. |
Dominance | Situation in which one allele is expressed over a second allele. |
Gene | A portion of a DNA molecule that serves as the basic unit of heredity. |
Genotype | The genetic makeup of an individual organism expressed with letters. |
Genetic Crossing | The deliberate breeding of two different individuals that results in offspring that carry part of the genetic material of each parent. |
Mitosis | Asexual cell division where one parent cell divides and produces two identical daughter cells |
Heterozygous | A pair of genes where one allele is dominant and one allele is recessive. |
Homozygous | A pair of genes where both alleles are dominant or both are recessive. |
Hybrid | An animal or plant resulting from a cross between genetically unlike individuals. |
Independent Assortment | Mendel's law that states that traits are transmitted to offspring independently of one another. |
Phenotype | The physical appearance of an organism as distinguished from its genetic makeup. |
Punnett Square | A type of grid that can indicate all the possible outcomes of a genetic cross. |
Recessive | An allele whose phenotype is masked when paired with a dominant allele. |

Meiosis | a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell |
Purebred | A homozygous trait where BOTH alleles are the same. Ex. TT or tt |
Meiosis | When gametes are created and result in one allele in the sex cells. |
Codominance | When two dominant traits show in an offspring |
