| Question | Answer |
| What are genetics | genetics is the study of inherited characteristics called traits |
| what are alleles | variations of genes |
| what do alleles do? | Alleles occupy the same position on homologous chromosomes |
| what is pure breeding? | When all the individuals have the same genetic information |
| what are homologous chromosomes | chromosomes with genes for particular characteristics at the same location |
| what is heterozygous? | having two different alleles on homogolous chromosomes |
| what is mutation? | a mistake that is made as dna is copied causing a change to the base sequence |
| what is a mutagen | an agent that causes mutation |
| whats a pedigree | a diagram used to show patterns of inheritance over generations |
| what is plasmid | ring of dna found in bacteria |
| what are traits | inhertied characteristics |
| what is a recessive trait | a trait that remains hidden in the heterozygous condition and only seen in the homozygous condition |
| what is genotype | genetic information carried by an individual |
| what is a genome | the complete set of DNA including all the genes of a cell individual or species |
| what is a dominant trait | the trait that is observed in the outward appearance of a heterozygous individual |
| what is dna profiling | a pattern of dna fragments unique to each individual |
| what is a carcinogen | a mutagen that can lead to cancer |
| what is gene splicing | the process used to add a gene into or remove genes from DNA |
| what is gene therapy | the process of replacing a defective gene with a normal gene |
| what is recombinant dna technology | technology that allows dna to be recombined with other genes |
| what are sex linked genes | genes present on the sex chromosomes |
