Pedigree records are kept by plants breeders and pedigree-based selection is popular in several plant species. Plant pedigrees are different from that of humans, particularly as plant are hermaphroditic – an individual can be male or female and mating can be performed in random combinations, with inbreeding loops. Also plant pedigrees may ...
Ahnentafel, also known as the Eytzinger Method, Sosa Method, and Sosa-Stradonitz Method, allows for the numbering of ancestors beginning with a descendant.This system allows one to derive an ancestor's number without compiling the complete list, and allows one to derive an ancestor's relationship based on their number.
Illustrative pedigree. Pedigrees are diagrams of familial connections between individuals and their ancestors, and possibly between other members of the group that share genetical inheritance with them. They are relationship maps. A pedigree can be analyzed, therefore, to reveal coefficients of inbreeding and co-ancestry.
Genealogy software products differ in the way they support data acquisition (e.g. drag and drop data entry for images, flexible data formats, free defined custom attributes for persons and connections between persons, rating of sources) and interaction (e.g. 3D-view, name filters, full text search and dynamic pan and zoom navigation), in reporting (e.g.: fan charts, automatic narratives ...
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. [ citation needed ] Definition
A personality test is a method of assessing human personality constructs.Most personality assessment instruments (despite being loosely referred to as "personality tests") are in fact introspective (i.e., subjective) self-report questionnaire (Q-data, in terms of LOTS data) measures or reports from life records (L-data) such as rating scales.
The Elston–Stewart algorithm is an algorithm for computing the likelihood of observed data on a pedigree assuming a general model under which specific genetic segregation, linkage and association models can be tested. It is due to Robert Elston and John Stewart. It can handle relatively large pedigrees providing they are (almost) outbred.
Estimation in biology/animal breeding using standard ANOVA/REML methods of variance components such as heritability, shared-environment, maternal effects etc. typically requires individuals of known relatedness such as parent/child; this is often unavailable or the pedigree data unreliable, leading to inability to apply the methods or requiring strict laboratory control of all breeding (which ...
