| Term | Definition |
|---|---|
| Allele | One of the possible types of a gene. Most genes have a dominant and recessive one. |
| Autosome | Any chromosome that is not a sex chromosome. |
| Codominance | Is when two genes are evenly shown |
| Dihydrid | An organism that is heterozygous for 2 traits |
| Dominant Allele | It is more influential over the recessive allele |
| Genotype | An organism's unique genetics |
| Heterozygous | having a recessive and dominant allele. Two differents ones |
| Homozygous | “Homo” Having the same alleles |
| Monohybrid | hybrid that is heterozygous for one trait |
| Multiple Allele | There are more than 2 alleles |
| Phenotype | appearance that is the way it is because of the environment and genotype |
| Punnet Square | a machine used to forecast the product of easy genetic crosses |
| Recessive Allele | innate factor shown in phenotype but only when genotype is homozygous |
| Sex Chromosome | chromosome that decides sex so either male XY or female XX |
| Sex-linked Trait | a certain trait that is with the sex chromosome but not to do with sexual stuff |
| Test Cross | crossing of the dominant and recessive phenotype |
| Apoptosis | the cell dies because a lot of cellular events have pushed the cell to dying |
| Cell Cycle | a cycle that has cell growth as well as division |
| Centriole | Is cell organelle. Found in pairs. Can organize spindle fibres during division |
| Centromere | area where sister chromatids bind to each other where fibres attach |
| Chromatin | Holds DNA. Is what chromosomes are made of |
| Chromosome | Hold your genes. See during division |
| Crossing-Over | transfer of genes between homologous chromosome .Makes offspring unique |
| Cytokinesis | splitting of the cell in either meiosis or mitosis |
| Diploid(2n) | double # of chromosomes in gametes |
| Chromosome Number | characteristic # of chromosome in cell in certain species |
| Gamete | sexual reproduction cell that makes zygote |
| Haploid(n) Chromosome Number | haploid number (n) is the # of chromosomes in a gamete |
| Homologous Chromosomes | Chromosomes that pair up for meiosis |
| Meiosis | a type of cell division used for sexual reproduction |
| Mitosis | cell division where daughter has same genetic makeup. Used for growth and repair. |
| Nondisjunction | homologous chromosomes failing to split during meiosis |
| Somatic Cell | Any cell that is not a reproductive cell |
| Synapsis | homologous chromosomes pair in meiosis in prophase 1 |
