- 1What are geneticsgenetics is the study of inherited characteristics called traits
- 2what are allelesvariations of genes
- 3what do alleles do?Alleles occupy the same position on homologous chromosomes
- 4what is pure breeding?When all the individuals have the same genetic information
- 5what are homologous chromosomeschromosomes with genes for particular characteristics at the same location
- 6what is heterozygous?having two different alleles on homogolous chromosomes
- 7what is mutation?a mistake that is made as dna is copied causing a change to the base sequence
- 8what is a mutagenan agent that causes mutation
- 9whats a pedigreea diagram used to show patterns of inheritance over generations
- 10what is plasmidring of dna found in bacteria
- 11what are traitsinhertied characteristics
- 12what is a recessive traita trait that remains hidden in the heterozygous condition and only seen in the homozygous condition
- 13what is genotypegenetic information carried by an individual
- 14what is a genomethe complete set of DNA including all the genes of a cell individual or species
- 15what is a dominant traitthe trait that is observed in the outward appearance of a heterozygous individual
- 16what is dna profilinga pattern of dna fragments unique to each individual
- 17what is a carcinogena mutagen that can lead to cancer
- 18what is gene splicingthe process used to add a gene into or remove genes from DNA
- 19what is gene therapythe process of replacing a defective gene with a normal gene
- 20what is recombinant dna technologytechnology that allows dna to be recombined with other genes
- 21what are sex linked genesgenes present on the sex chromosomes
