Mutation
Chromosomes Mutations
Deletion
Inversion
Translocation
Nondisjunction
Duplication
Gene Mutations
Point Mutations
Substituatons
Insertions
Deletions
Frameshift
Heritable change in
genetic material or
character of an organism
Indivisuals showing these changes are known as mutants
Individuals showing these changes are known as mutants
Factor or agents causing mutation are known as mutagens
Mutation which causes changes in base sequence of a gene are known as gene mutation or point mutation
mutant alleles are recessive to
their wild type or normal alleles
Most mutations have harmful effect
but some mutations are beneficial
Spontaneous mutations occur at very low rate
Some genes show high rate of mutation such genes are called mutable gene
Based on tissue of origin
Somatic mutations
Somatic mutations pass from one progeny to the next in asexually reproducing species.
-mutation occurring in somatic cell
Germinal Mutation
mutation occur in gametic cells or reproductive cells
germinal mutation are transmitted to the next generation
Based on direction of mutation
Forward Mutation
When mutation occurs from the normal/wild type allele to mutant allele are known as forward mutation
Reverse Mutation
When mutation occurs in reverse direction that is from mutant allele to the normal/wild type allele
