| A | B |
|---|
| allele | alternative forms of a gene |
| anther | the male part of a flower |
| cross-pollination | using the sperm from one flower to pollinate another |
| dominant | the trait that masks all other and is thus always expressed |
| F1 generation | first filial generation |
| F2 generation | second filial generation |
| genetics | the study of how charactersitics are passed from the parents to the offspring |
| heredity | the transmission of traits from parents to offspring |
| law of independent assortment | applies to genes located on separate chromosomes where chromosomes separate independently of one another |
| P1 generation | the parental generation |
| pollination | fertilization in flowers |
| pure | organisms that always produce offspring with the same traits |
| reccessive | the trait that is expressed only when paired with another reccessive allele |
| self-pollination | using sperm from the same flower for pollination |
| stigma | the female parts of a flower |
| strain | plants that are pure for a particular trait |
| trait | a category within which alternate characteristics can be observed |
| codominance | when both alleles are expressed in a heterozygous individual |
| complete dominance | when heterozygous and homozygous dominant individuals are indistinguishable in phenotype |
| dihybrid cross | a cross involving two traits |
| genotype | the genetic makeup of an organism |
| genotypic ratio | the ratio of genotypes in a cross |
| heterozygous | when an organism has different alleles for a trait |
| homozygous | when an organism has two of the same alleles for a trait |
| incomplete dominance | when two or more alleles influence the phenotype resulting in an intermediate between the dominant and the recessive |
| monohybrid cross | a cross involving one trait |
| phenotype | the appearance of an organism as a result of the genotype |
| phenotypic ratio | the ratio of phenotypes in a cross |
| probability | the likelihood that a particular event will occur |
| Punnett square | a diagram used to aid in the probabilty that a certain traits will be inherited by the offspring |
| testcross | where an individual of unknown genotype is crossed with a homozygous individual |
