| homologous | description of chromosomes that occur in pairs; having a corresponding structure |
| diploid | description of a cell that contains double set of chromosomes, one from each parent. |
| haploid | description of cells that contain a single set of chromosomes |
| meiosis | process that produces haploid gametes from diploid cells. |
| Crossing-Over | process by which homologous chromosomes exchange portions of their chromatids during meiosis. |
| heterozygous | organism that has two different alleles for the same trait and is said to be hybrid for that particular trait. |
| linked genes | genes that are inherited together and do not undergo independent assortment |
| recombinant | Individual organism with new combinations of genes |
| Autosomes | chromosome that is not a sex chromosome |
| nondisjunction | failure of homologous chromosomes to separate normally durning meiosis |
| Homozygous | organism that has two identical alleles for a particular trait. |
| Gene | Segments of DNA that codes for a particular protein |
| Chromosome | Threadlike stucture in a cell that contains the genetic information that is passed on from one generation of cells to the next |
| Trait | characteristics that a living thing can pass on to its young |
| Dominant | form of a gene that is expressed even if present with a contrasting recessive allele |
| Recessive | Description of a form of a gene(allele)that is only expressed in only the homozygous stage. |
| Phenotype | physical characteristics of a organism |
| Genotype | Genetic make up of an organism |
| Allele | one of a number of different form of the same gene for a specific trait |
