| Term | Definition |
|---|---|
| Dominant | Allele that masks, the effect of the other |
| Recessive | Allele that is expressed when both are present |
| Allele | Alternative form of a gene |
| Genotype | The genetic make-up of the organism |
| Phenotype | Measurable characteristics of an organism that are determined by the genotype |
| Homozygous | Having identical alleles for a particular trait |
| Heterozygous | Having non-identical alleles for a particular trait |
| Incomplete dominance | When two traits mix to create a new i.e. new colour |
| Codominance | When both dominant traits show up i.e. spotted |
| Incomplete dominance | The type of dominance that creates an intermediate phenotype (remember to think of "in" in intermediate and "in" in the dominance type) |
| How many phonotypes will there be for Codominance | This type of dominance has 3 phenotypes |
| Codominance | When both of the parents trains show up in the offspring |
| Deletion mutation | When a base is lost |
| Insertion mutation | When a base is inserted in to the sequence |
| Substitution mutation | When a bases is subbed for another |
| Frameshift | Can occur from a deletion or insertion mutation |
| Missense | When the substitution changes the amino acid that will be created |
| Silent | When a substitution does not change the amino acid created |
| Nonsense | When a substitution changes the amino acid to a "stop" |
| If something is X-linked, how many alleles does the male need to inherit to make it so? | One (therefore, x-linked traits can show up more frequently in a male) |
| Gene | A section of DNA that codes for a trait (think of it as a recipe - while the DNA is the cookbook) |
| Allele | The different variations of the gene - like for eye colour. An individual will inherit two alleles. Humans have 2 alleles for each gene (this is why we are called diploid) |
