Pseudoallelism is a state in which two genes with similar functions are located so close to one another on a chromosome that they are genetically linked. [1] [2] This means that the two genes (pseudoalleles) are nearly always inherited together.
Coalescent theory is a model of how alleles sampled from a population may have originated from a common ancestor.In the simplest case, coalescent theory assumes no recombination, no natural selection, and no gene flow or population structure, meaning that each variant is equally likely to have been passed from one generation to the next.
A 1994 article in Behavior Genetics based on a study of Swedish monozygotic and dizygotic twins found the heritability of the sample to be as high as 0.80 in general cognitive ability; however, it also varies by trait, with 0.60 for verbal tests, 0.50 for spatial and speed-of-processing tests, and 0.40 for memory tests. In contrast, studies of ...
The following outline is provided as an overview of and topical guide to genetics: . Genetics – science of genes, heredity, and variation in living organisms. [1] [2] Genetics deals with the molecular structure and function of genes, and gene behavior in context of a cell or organism (e.g. dominance and epigenetics), patterns of inheritance from parent to offspring, and gene distribution ...
Genetic analysis is the overall process of studying and researching in fields of science that involve genetics and molecular biology. There are a number of applications that are developed from this research, and these are also considered parts of the process. The base system of analysis revolves around general genetics.
Overdominance is a phenomenon in genetics where the phenotype of the heterozygote lies outside the phenotypical range of both homozygous parents. Overdominance can also be described as heterozygote advantage regulated by a single genomic locus, wherein heterozygous individuals have a higher fitness than homozygous individuals.
Students, teachers and parents will find the glossary an easy-to-use, always available learning source on genetics. — Courtesy: National Human Genome Research Institute [ 1 ] The first version was published in English online in September 1998 by the NHGRI Office of Science Education under the title of " Talking Glossary of Genetics ". [ 2 ]
They can be estimated using individual-level data from twin studies and molecular genetics, or even with GWAS summary statistics. [ 10 ] [ 11 ] Genetic correlations have been found to be common in non-human genetics [ 12 ] and to be broadly similar to their respective phenotypic correlations, [ 13 ] and also found extensively in human traits ...
