Dynamic selection procedures for constrained inbreeding and their consequences for pedigree development

Genetical Research, 1998
A novel selection algorithm for maximizing genetic response while constraining the rate of inbreeding is presented. It is shown that the proposed method controls the rate of inbreeding by maintaining the sum of squared genetic contributions at a constant value and represents an improvement on previous procedures.

Impact of nonadditive genetic effects in the estimation of breeding values for fertility and correlated traits [PDF]

, 2005
The effects of inbreeding, heterosis, recombination loss, and percentage Holstein on the estimation of predicted transmitting abilities for fertility traits (calving interval, number of days from calving to first insemination, nonreturn rate, number of ...

Assessing genetic diversity in a reintroduced Mediterranean griffon vulture Gyps fulvus population to inform long‐term conservation management

Wildlife Biology, EarlyView.
Reintroductions play a key role in conservation biology. Their long‐term success strongly depends on maximizing the genetic diversity of founders, as well as on ensuring ecological connectivity with adjacent populations. Accordingly, evaluating the conservation status of reintroduced populations to limit the loss of their genetic diversity requires ...

A model to infer the demographic structure evolution of endangered donkey populations

Animal, 2017
Stemming from The Worldwide Donkey Breeds Project, an initiative aiming at connecting international researchers and entities working with the donkey species, molecularly tested pedigree analyses were carried out to study the genetic diversity, structure ...

Removing exogenous information using pedigree data [PDF]

, 2011
Management of certain populations requires the preservation of its pure genetic background. When, for different reasons, undesired alleles are introduced, the original genetic conformation must be recovered.

Biology, ecology, and conservation of the Italian hare Lepus corsicanus: a review

Wildlife Biology, EarlyView.
The Italian hare Lepus corsicanus, an endemic lagomorph of Italy, serves as a critical case study in evolutionary biology and conservation. Once taxonomically debated, modern genetic and morphological analyses confirm its status as a distinct Pleistocene lineage restricted to the central‐southern Italian Peninsula and Sicily.

Meiotic recombination shapes precision of pedigree- and marker-based estimates of inbreeding [PDF]

Heredity, 2016
The proportion of an individual's genome that is identical by descent (GWIBD) can be estimated from pedigrees (inbreeding coefficient 'Pedigree F') or molecular markers ('Marker F'), but both estimators come with error. Assuming unrelated pedigree founders, Pedigree F is the expected proportion of GWIBD given a specific inbreeding constellation ...

Heightened threats to small woodland caribou populations in Canada and key considerations for their persistence Menaces pesant sur les petites populations de caribou des bois au Canada et considérations essentielles à leur rétablissement

Wildlife Monographs, EarlyView.
Abstract Woodland caribou (Rangifer tarandus) are one of the most iconic wildlife species in Canada. These large ungulates depend on undisturbed, interconnected assemblages of mature and old‐growth conifer forests for survival, and exhibit life‐history traits typical of K‐selected species (i.e., low reproductive rates, long generation times, and slow ...

EFFECT OF INBREEDING ON MORTALITY OF CAPTIVE TIGER [PDF]

Exploratory Animal and Medical Research, 2017
A study was carried out on the captive tigers of Nandankanan zoo, Odisha, India, to conclude any deleterious effect of inbreeding on mortality. A pedigree path analysis of 342 tigers was done to estimate the inbreeding coefficient of each tiger from ...

Inbreeding, pedigree size, and the most recent common ancestor of humanity [PDF]

Journal of Theoretical Biology, 2009
How many generations ago did the common ancestor of all present-day individuals live, and how does inbreeding affect this estimate? The number of ancestors within family trees determines the timing of the most recent common ancestor of humanity. However, mating is often non-random and inbreeding is ubiquitous in natural populations.
