| A | B |
| allele | different versions of one gene usually represented by a capital or lower case letter ex: Pea pods have to heights T and t |
| homozygous | the two alleles are the same |
| heterozygous | the two alleles are different |
| dominant | represented by capital letter/if dominant allele is present, it will be used |
| recessive | the allele that is not represented; to be used all the alleles have to be recessive used as a small letter |
| F1 generation | the offspring of a parent generation |
| F2 generation | the gneration produced from the original offspring of the parent generation |
| p-generation | parental generation/the original pairs of alleles |
| genotype | genetic make up of an organism |
| phenotype | physical characterisitic of an organism |
| incomplete dominance | situation in which one allele is not completely dominant over another |
| co-dominance | situation in which both alleles of a gene contribute to the phenotype of the organism |
| test cross | when you write out the sets of allelles to be used in a punnett square |
| true breeding | pure breeding/a cross of the same species and you will alwys get the same result |
| gamete | specialized cell involved in sexual reproduction |
| trait | a specific characterisitc such as seed color or plant height |
| Punnett square | the diagram used to determine the genotypes/phenotypes |
