| Genotype | an organism's genetic makeup... the genes found in the chromosomes from mom and dad, either if we can see it or not. |
| Phenotype | the outward expression of an allele or alleles |
| Allele | An alternate for of the same gene for a given trait. Rr Mm |
| Genes | The unit of hereditary information that controls traits of a particular organism |
| monohybrid cross | A combination of two different types of genes (4 square) |
| dihybrid cross | a hybrid that is heterozygous for alleles of two different genes MmLl (16 square) |
| test cross | the cross of a homozygous recessive and an unknown genotype resulting in an offspring with observable phetypes |
| incomplete dominace | A pattern of inheritance in which two alleles in a heterozygote are partially expressed (red and white make pink) |
| codominance | a pattern of inheritance in which both alleles in a heterozygote are fully expressed (black and white chicken) |
| sex-linkage | a gene located on a sex chromosome ( x or y) |
| pedigree | a chart that shows how a trait is inherited throughout a family |
