Variation in actual relationship among descendants of inbred individuals [PDF]
, 2012 In previous analyses, the variation in actual, or realized, relationship has been derived as a function of map length of chromosomes and type of relationship, the variation being greater the shorter the total chromosome length and the coefficient of ...

Inbreeding coefficients and coalescence times
Genetics Research, 1991 SummaryThis paper describes the relationship between probabilities of identity by descent and the distribution of coalescence times. By using the relationship between coalescence times and identity probabilities, it is possible to extend existing results for inbreeding coefficients in regular systems of mating to find the distribution of coalescence ...

Consanguinity marriage and fertility outcome health in the middle Euphrates of Iraq
مجلة علوم ذي قار, 2019 The inbreeding coefficient refers to the degree of advancing of any society. In 2006 an experiment was conducted to find the inbreeding coefficient in the middle Euphrates area of Iraq (Al-Qadisiyia and Babylon) and to study the relationship between ...

Facial attractiveness is only weakly linked to genome–wide heterozygosity
Frontiers in Psychology, 2023 IntroductionIt has been frequently suggested that overall genomic heterozygosity and, particularly, heterozygosity of loci on the so-called major histocompatibility complex (MHC), which is responsible for the recognition of foreign substances/ pathogens ...

Phase Transition in Sexual Reproduction and Biological Evolution
, 2008 Using Monte Carlo model of biological evolution we have discovered that populations can switch between two different strategies of their genomes' evolution; Darwinian purifying selection and complementing the haplotypes. The first one is exploited in the

PLANTS, PEOPLE, PLANET, EarlyView.The jewel‐like flowers of Thismia are as rare as they are beautiful, often recorded from only a single site per species. Access to 15 populations of T. kobensis has enabled an uncommon, range‐wide assessment of morphology, genetics, and fungal partners. Our analyses showed that T.

Purging of inbreeding depression within the Irish Holstein-Friesian population
Genetics Selection Evolution, 2009 The objective of this study was to investigate whether inbreeding depression in milk production or fertility performance has been partially purged due to selection within the Irish Holstein-Friesian population.

Wildlife Biology, EarlyView.Effective population size (Ne) is a useful parameter to evaluate the long‐term viability of populations. While obtaining enough field data from wild populations to estimate Ne directly is challenging, molecular techniques applied to non‐invasive samples provide an appealing alternative.
