Silent mutations, also called synonymous or samesense mutations, are mutations in DNA that do not have an observable effect on the organism's phenotype. The phrase silent mutation is often used interchangeably with the phrase synonymous mutation ; however, synonymous mutations are not always silent, nor vice versa.
Mannheim defined a generation (note that some have suggested that the term cohort is more correct) to distinguish social generations from the kinship (family, blood-related generations) [2] as a group of individuals of similar ages whose members have experienced a noteworthy historical event within a set period of time.
Hermann J. Muller (1890–1967), who was a 1946 Nobel Prize winner, coined the terms amorph, hypomorph, hypermorph, antimorph and neomorph to classify mutations based on their behaviour in various genetic situations, as well as gene interaction between themselves. [1] These classifications are still widely used in Drosophila genetics to ...
The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child. There are over 6,000 known genetic disorders in humans.
In the anthropological study of kinship, a moiety (/ ˈ m ɔɪ ə t i /) is a descent group that coexists with only one other descent group within a society.In such cases, the community usually has unilineal descent (either patri-or matrilineal) so that any individual belongs to one of the two moiety groups by birth, and all marriages take place between members of opposite moieties.
[c] [20] [21] By this, de Vries meant that a new form of the plant was created in a single step (not the same as a mutation in the modern sense); no long period of natural selection was required for speciation, and nor was reproductive isolation. [22] In the view of the historian of science Peter J. Bowler, De Vries used the term to mean [1]

The Silent Generation, also known as the Traditionalist Generation, is the Western demographic cohort following the Greatest Generation and preceding the baby boomers. The generation is generally defined as people born from 1928 to 1945. [1] By this definition and U.S. Census data, there were 23 million Silents in the United States as of 2019. [2]
