Example of a pedigree chart using Ahnentafel numbering A pedigree chart is a diagram that shows the occurrence of certain traits through different generations of a family, [ 1 ] [ 2 ] most commonly for humans , show dogs , and race horses .
Genetics tries to identify which traits are inherited and to explain how these traits are passed from generation to generation. Some traits are part of an organism's physical appearance, such as eye color or height. Other sorts of traits are not easily seen and include blood types or resistance to diseases. Some traits are inherited through ...
Convergent evolution—the repeated evolution of similar traits in multiple lineages which all ancestrally lack the trait—is rife in nature, as illustrated by the examples below. The ultimate cause of convergence is usually a similar evolutionary biome , as similar environments will select for similar traits in any species occupying the same ...
Heredity of phenotypic traits: a father and son with prominent ears and crowns. DNA structure. Bases are in the centre, surrounded by phosphate–sugar chains in a double helix. In humans, eye color is an example of an inherited characteristic: an individual might inherit the "brown-eye trait" from one of the parents. [1]
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.
Genomic imprinting, which determines whether some genes inherited from the mother and father get expressed. [10] The expressivity of a gene can be influenced by the environmental conditions. [11] For example, pigmentation in the fur of Himalayan rabbits is determined by the C gene, the activity of which is dependent on temperature. [12]
It differs from divergent evolution as the species involved do not descend from a closely related common ancestor and the traits accumulated are similar. [4] An example of convergent evolution is the development of flight in birds, bats, and insects, all of which are not closely related but share analogous structures allowing for flight. [8]
The social insects provide good examples of organisms with what appear to be kin selected traits. The workers of some species are sterile, a trait that would not occur if individual selection was the only process at work. The relatedness coefficient r is abnormally high between the worker sisters in a colony of Hymenoptera due to haplodiploidy.
