Depending on: A. The Type of Cell Involved 1. Somatic mutations • Mutations that are in the somatic tissues of the body. • Mutations are not transmitted to progeny. • The extent of the phenotypic effect depends upon whether the mutation is dominant or recessive (dominant mutations generally have a greater effect). • The extent of the phenotypic effect depends upon whether it occurs early or late in development (early arising mutations have a greater effect). 2. Germinal mutations • Mutations that are in the germ tissues of the body. • Mutations may be transmitted to progeny • Dominant mutations are seen in first generation after the mutation occurs • If a female gamete containing an X-linked mutation is fertilized, the males will show the mutant phenotype • Recessive mutations will only be seen upon the chance mating with an individual carrying the recessive allele too; thus, the recessive mutation may remain hidden for many generations B. Mode of Origin (1) Spontaneous mutations The spontaneous mutations occur suddenly in the nature and their origin is unknown. They are also called “background mutation” and have been reported in many organisms such as, Oenothera, maize, bread molds, microorganisms (bacteria and viruses), Drosophila, mice, man, etc. (2) Induced mutations Besides naturally occurring spontaneous mutations, the mutations can be induced artificially in the living organisms by exposing them to abnormal environment such as radiation, certain physical conditions (i.e., temperature) and chemicals. C. Direction of Mutation According to their mode of direction following types of mutations have been recognized: --------------------------------------------------------------------------------------------------------------------------- Join this channel to get access to perks: Sign up now on our website at https://members.drnajeeblectures.com/...    / @doctornajeeb   Follow us on Facebook :-   / drnajeeb   Follow us on Instagram :-   / drnajeeblectures
