Just as birds have wings, man has language. -- George Henry Lewes
This chapter provides a glossary of terms.12.1
- ancestor loss coefficient
- See: pedigree completeness.
- coefficient of ancestral inbreeding
- The probability that an individual jas inherited an allele that has undergone inbreeding in the past at least once.
- coefficient of inbreeding
- Probability that two alleles selected at random are identical by descent.
- coefficient of partial inbreeding
- The probability that the alleles at an arbitrary locus in an individual are identitical-by-descent, and that the alleles were derived from an allele in a particular founder.
- coefficient of relationship
- Proportion of genes that two individuals share on average.
- effective ancestor number
- The number of equally-contributing ancestors, not necessarily founders, needed to produce a population with the heterozygosity of the studied population [Boichard, Maignel, and VerrierBoichard
- effective founder number
- The number of equally-contributing founders needed to produce a population with the heterozygosity of the studied population [LacyLacy1989].
- effective population size
- The effective population size is the size of an ideal population that would lose heterozygosity at a rate equal to that of the studied population [Falconer and MacKayFalconer and
- An animal with unknown parents that is assumed to be unrelated to all other founders.
- internal report
- A PyPedal() report that is intended for use by other PyPedal() procedures, such as plotting
routines, and not for printing.
- numerator relationship matrix
- Matrix of additive genetic covariances among the animals in a population.
- A PyPedal pedigree consists of a Python list containing instances of PyPedal NewAnimal() objects.
- pedigree completeness
- The proportion of known pedigree information for an arbitrary number of generations.
- Many calculations require that the animals in a pedigree be ordered from oldest to youngest, with sires and dams preceding offspring, and renumbered starting with 1. This is a computational necessity, and results in an animal's ID (animalID) being changed to reflect that animal's order in the pedigree. All animals have their original IDs stored in their originalName attribute.
- The process of arranging animals in a pedigree so that parents appear before their offspring; this is a necessary step in renumbering a pedigree.
