The evolutionary ecology of inbreeding depression in wild plant populations and its impact on plant mating systems

open access: yesFrontiers in Plant Science
Inbreeding depression, the reduced fitness of inbred relative to outbred individuals was described more than two centuries ago, long before the development of population genetics.

Social effects of inbreeding associated with parental care [PDF]

open access: yes, 2014
Inbreeding is associated with reduced fitness, a phenomenon known as inbreeding depression. I investigated direct and indirect effects of inbreeding on social traits associated with parental care in the burying beetle, Nicrophorus vespilloides.

Predicting rates of inbreeding: in populations undergoing selection

open access: yes, 2000
Tractable forms of predicting rates of inbreeding (Delta F) in selected populations with general indices, nonrandom mating, and overlapping generations were developed, with the principal results assuming a period of equilibrium in the selection process ...

EFFECT OF INBREEDING ON SOME PERFORMANCE TRAITS IN SAHIWAL CATTLE

open access: yesPakistan Veterinary Journal, 2001
Pedigree, breeding and performance records of a purebred Sahiwal herd maintained at Livestock Experiment Station, Jahangirabad, Khanewal during the period 1939-97 were utilised for the present study. The effect of inbreeding on various performance traits

On the prediction of simultaneous inbreeding coefficients at multiple loci

open access: yes, 2004
A new deterministic method for predicting simultaneous inbreeding coefficients at three and four loci is presented. The method involves calculating the conditional probability of IBD (identical by descent) at one locus given IBD at other loci, and ...

Minimizing inbreeding by managing genetic contributions across generations

open access: yes, 2003
Here we present the strategy that achieves the lowest possible rate of inbreeding (DeltaF) for a population with unequal members of sires and dams with random mating. This new strategy results in a DeltaF as much as 10% lower than previously achieved.

Commonly used genomic estimators of individual inbreeding in livestock

open access: yes
: Management of inbreeding is one of the crucial parts of breeding programs in livestock populations. Traditionally, the inbreeding coefficient is calculated using pedigree data; however, it can also be estimated from genomic data.

THE EFFECT OF IMPROVED REPRODUCTIVE-PERFORMANCE ON GENETIC GAIN AND INBREEDING IN MOET BREEDING SCHEMES FOR BEEF-CATTLE

open access: yes, 1995
The effect of improved reproductive techniques on genetic progress and inbreeding was investigated in MOET (multiple ovulation and embryo transfer) schemes for beef cattle.

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

open access: yes, 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 ...
