Terms Related to Mutation

• Germ-Line Mutation

  Any detectable and heritable alteration in the lineage of germ cells. Mutations in these cells (i.e., "generative" cells ancestral to the gametes) are transmitted to ...

• Genetic Marker

  A phenotypically recognizable genetic trait which can be used to identify a genetic locus, a linkage group, or a recombination event.

• Point Mutation

  A mutation caused by the substitution of one nucleotide for another. This results in the DNA molecule having a change in a single base pair.

• Genetic Recombination

  Production of new arrangements of genes by various mechanisms such as assortment and segregation, crossing over, gene conversion, transformation, conjugation, transduction, F-duction, or mixed infection ...

• Nonsense Mutation Suppressor Genes

  Genes that have a suppressor allele or suppressor mutation (SUPPRESSION, GENETIC) which cancels the effect of a previous mutation, enabling the wild-type phenotype to be ...

• Genetic Suppression

  The restoration of the wild-type phenotype in an organism possessing a mutationally altered genotype. The effects of the mutation may be suppressed by a second ...

• Genetic Load

  The study of the genetic composition of populations and of the effects of factors such as selection, population size, mutation, migration, and genetic drift on ...
