Alleles and Complimentation- Definitions
Cards in this deck (22)
- 1GenotypeGenetic Makeup- of an individual, group or species
- 2PhenotypeViewable Organism Traits
- 3AlleleOne of a series of possible alternative forms of a given gene
- 4GeneHereditary unit that occupies a specific locus in the organism's genome
- 5Amorph MutationGenetic Null- Complete loss of all gene function
- 6HypomorphReduced gene function
- 7HypermorphIncreased gene function
- 8AntimorphA mutant that inhibits wild type function
- 9NeomorphNew gene function
- 10Dominance- Referring to Allelic interactionEffects genotype, not inheritence
- 11Phenotypic InvestigationUsed to determine dominance and recessiveness in genotypes
- 12Recessive AllelesOnly effect phenotype when present in homozygous form
- 13Yeast- Diploid or Haploid?Exists in both forms- if starved of nitrogen, they form haploid spores
- 14Yeast as a Model OrganismDominant/Recessive traits obvious when spores breed together
- 15MutagenesisAn event capable of causing mutation- done in labs using chemicals/UV
- 16Allelic MutationsWhere induced mutations all occur to the same allele
- 17Non-Allelic MutationsMutations occurring to different alleles that effect the same pathway
- 18Dominant Negative MutationA mutation that adversely effects the activity of the wild type allele (if present)
- 19TRF2A protein that binds to telomeric DNA using it's Myb domain
- 20Mutant TRF2Example of a dominant negative mutation- mutant TRF2 lacking a Myb domain strips the w.t of its Myb domain
- 21MybPart of TRF2 required to bind to the telomere
- 22EpistasisWhere the presence of one GENE masks the expression of another
