This is a list of gene families or gene complexes, i.e. sets of genes which are related ancestrally and often serve similar biological functions.These gene families typically encode functionally related proteins, and sometimes the term gene families is a shorthand for the sets of proteins that the genes encode.
If the genes of a gene family encode proteins, the term protein family is often used in an analogous manner to gene family. The expansion or contraction of gene families along a specific lineage can be due to chance, or can be the result of natural selection. [2] To distinguish between these two cases is often difficult in practice.
The human cyclophilin family, as represented by the structures of the isomerase domains of some of its members. A protein family is a group of evolutionarily related proteins.In many cases, a protein family has a corresponding gene family, in which each gene encodes a corresponding protein with a 1:1 relationship.
Family resemblance refers to physical similarities shared between close relatives, especially between parents and children and between siblings. [1] In psychology , the similarities of personality are also observed.
Gene–environment interaction occurs when genetic factors and environmental factors interact to produce an outcome that cannot be explained by either factor alone. [6] For example, a study found that individuals carrying the genetic variant 5-HTT (the short copy) that encodes the serotonin transporter were at a higher risk of developing depression when exposed to adverse childhood experiences ...
Behavioural genetics, also referred to as behaviour genetics, is a field of scientific research that uses genetic methods to investigate the nature and origins of individual differences in behaviour.
Dual inheritance theory (DIT), also known as gene–culture coevolution or biocultural evolution, [1] was developed in the 1960s through early 1980s to explain how human behavior is a product of two different and interacting evolutionary processes: genetic evolution and cultural evolution.
Gene clusters often result from expansions of a single gene caused by repeated duplication events, and may be observed near one another on the same chromosome or on different, but homologous chromosomes. An example of a gene cluster is the Hox gene, which is made up of eight genes and is part of the Homeobox gene family.
