GWAS detect genetic variants that predict the incidence of a disease. For example, GWAS have identified genetic variants that are responsible for 10% of the heritability of Type II diabetes. [7] Under the Omnigenic Model, these detected variants may not be as important as other peripheral gene effects. [8]
One example is hearing impairment. Hearing impairment was tracked in one specific family and through seven generations all males were affected by this trait. However, this trait occurs rarely and has not been entirely resolved. [9] Y-chromosome deletions are a frequent genetic cause of male infertility.
An example of a family pedigree displaying an autosomal recessive trait. A pedigree is a diagram showing the ancestral relationships and transmission of genetic traits over several generations in a family. Square symbols are almost always used to represent males, whilst circles are used for females.
Mendelian traits behave according to the model of monogenic or simple gene inheritance in which one gene corresponds to one trait. Discrete traits (as opposed to continuously varying traits such as height) with simple Mendelian inheritance patterns are relatively rare in nature, and many of the clearest examples in humans cause disorders.
•List of human protein-coding genes page 2 covers genes EPHA1–MTMR3 •List of human protein-coding genes page 3 covers genes MTMR4–SLC17A7 •List of human protein-coding genes page 4 covers genes SLC17A8–ZZZ3 NB: Each list page contains 5000 human protein-coding genes, sorted alphanumerically by the HGNC-approved gene symbol.
A phenotypic trait is an obvious, observable, and measurable characteristic of an organism; it is the expression of genes in an observable way. An example of a phenotypic trait is a specific hair color or eye color. Underlying genes, that make up the genotype, determine the hair color, but the hair color observed is the phenotype.
Schematic karyogram of a human as seen on G banding, with annotated bands and sub-bands.It is a graphical representation of the idealized human diploid karyotype. Each row is vertically aligned at centromere level.
Peripatric speciation is a mode of speciation in which a new species is formed from an isolated peripheral population. [1]: 105 Since peripatric speciation resembles allopatric speciation, in that populations are isolated and prevented from exchanging genes, it can often be difficult to distinguish between them, [2] and peripatric speciation may be considered one type or model of allopatric ...
