The formal study of the pattern of a trait in a pedigree to determine such properties as its mode of inheritance, age of onset, and variability in phenotype.
pedigree analysisa technique in which patterns of inheritance are traced through several generations.
a table, chart, diagram, or list of an animal's ancestors, used in genetics in the analysis of mendelian inheritance, and in the prediction of productivity and breed quality in the offspring.
a useful basis for planning a program to eliminate an inherited defect; the analysis determines the probability that each prospective parent is homozygous for the normal gene, i.e. is not a carrier for the anomaly gene; potential parents with a probability of >95% can be used with confidence.
herds or flocks composed of animals whose pedigrees are known. Not necessarily stud herds or registered herd but the terms are usually synonymous.
the average of the predicted difference of the sire and the cow index of the dam. The pedigree index is allotted to the offspring.
use of an individual's pedigree to select breeding animals.
verification via breed societies and production testing agencies, horse stud books and race records are all used; checks via coat color, blood cell antigens may assist.
