Inverse inbreeding coefficient problems with an application to linkage analysis of recessive diseases in inbred populations

Richa Agarwala, Leslie G. Biesecker, Alejandro A. Schäffer
2000 Discrete Applied Mathematics  
The problem of choosing a pedigree is particularly interesting for diseases inherited in an autosomal recessive pattern in inbred populations because there are many possible paths of inheritance to choose  ...  We call such a problem an inverse inbreeding coe cient problem.  ...  Our work is also applicable to more large-scale epidemiology studies of inbred populations.  ...

An overview on quantitative and genomic tools for utilising dominance genetic variation in improving animal production

A. MÄKI-TANILA
2008 Agricultural and Food Science  
One possibility is the use of genomic tools in assessing populations for crossbreeding and in searching for major genes mediating dominance variation.  ...  Maximisation of heterosis can be done only on a temporary basis as a continued exploitation leads to stagnation in the overall genetic progress.  ...  Wall et al. (2005) found that the difference between a noninbred animal and an animal with an inbreeding coefficient of 10% had a 2.8 d increase in calving interval, a 1.7 d increase in days to first  ...

Both LD and relatedness are of interest on their own, as well as in their follow-up applications deriving overall measures of effective population size.  ...  The assessment of relatedness is also pivotal to construct meaningful mating plans and to avoid the negative consequences of inbreeding depression that might be detrimental especially in small, endangered  ...  The analysis of dense marker data is based on the assumption that SNPs are in sufficient linkage disequilibrium to regions of interests.  ...

Quantifying realized inbreeding in wild and captive animal populations

2015 Heredity  
This allowed us to determine whether any of these four regions was completely homozygous within an individual, which indicates IBD with high confidence.  ...  The inbreeding coefficient F Ped obtained from pedigrees is a valuable estimator of IBD, but pedigrees are not always available, and cannot capture inbreeding loops that reach back in time further than  ...  This study was funded by the Max Planck Society (BK), with the zebra finch study at Fowler's Gap funded by support to SCG from the Australian Research Council.  ...

Reconciling Differences in Pool-GWAS Between Populations: A Case Study of Female Abdominal Pigmentation in Drosophila melanogaster

L. Endler, A. J. Betancourt, V. Nolte, C. Schlotterer
2015 Genetics  
The degree of concordance between populations in the genetic architecture of a given trait is an important issue in medical and evolutionary genetics.  ...  Here, we address this problem, using a replicated pooled genome-wide association study approach (Pool-GWAS) to compare the genetic basis of variation in abdominal pigmentation in female European and South  ...  In the analysis of the European population, the SNPs within a group show strong linkage disequilibrium, resulting in almost identical allele frequency change.  ...

Heritability and segregation analysis of osteosarcoma in the Scottish deerhound

Jeffrey C. Phillips, Betty Stephenson, Marlene Hauck, John Dillberger
2007 Genomics  
The Scottish deerhound is a breed of dog with a N 15% incidence of osteosarcoma and represents an excellent spontaneously occurring large-animal model of the human disease.  ...  Inheritance of the putative high-risk allele was thus associated with N 75% risk of disease occurrence compared to the b5% baseline risk.  ...  Also, thanks to Arnold Saxton (University of Tennessee) for his thorough review of the manuscript, to Sandy Hasstedt (University of Utah) for her help with the jPAP software, and finally to Matthew Breen  ...
