Alleles and Complimentation- Definitions

Pregunta	Respuesta
Genotype	Genetic Makeup- of an individual, group or species
Phenotype	Viewable Organism Traits
Allele	One of a series of possible alternative forms of a given gene
Gene	Hereditary unit that occupies a specific locus in the organism's genome
Amorph Mutation	Genetic Null- Complete loss of all gene function
Hypomorph	Reduced gene function
Hypermorph	Increased gene function
Antimorph	A mutant that inhibits wild type function
Neomorph	New gene function
Dominance- Referring to Allelic interaction	Effects genotype, not inheritence
Phenotypic Investigation	Used to determine dominance and recessiveness in genotypes
Recessive Alleles	Only effect phenotype when present in homozygous form
Yeast- Diploid or Haploid?	Exists in both forms- if starved of nitrogen, they form haploid spores
Yeast as a Model Organism	Dominant/Recessive traits obvious when spores breed together
Mutagenesis	An event capable of causing mutation- done in labs using chemicals/UV
Allelic Mutations	Where induced mutations all occur to the same allele
Non-Allelic Mutations	Mutations occurring to different alleles that effect the same pathway
Dominant Negative Mutation	A mutation that adversely effects the activity of the wild type allele (if present)
TRF2	A protein that binds to telomeric DNA using it's Myb domain
Mutant TRF2	Example of a dominant negative mutation- mutant TRF2 lacking a Myb domain strips the w.t of its Myb domain
Myb	Part of TRF2 required to bind to the telomere
Epistasis	Where the presence of one GENE masks the expression of another
