Exploring inbreeding depression in Brazilian Angus cattle population using pedigree and genomic data

Frontiers in Genetics
IntroductionInbreeding depression refers to the decline in performance caused by increased levels of inbreeding, which results from mating individuals with common ancestors.

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 ...

A century of theories of balancing selection

Biological Reviews, EarlyView.
ABSTRACT Traits that affect organismal fitness are often highly genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature – after all – ‘selects’ the best genotypes at the expense of those that fall short.

Genomic data illuminates demography, genetic structure and selection of a popular dog breed

BMC Genomics, 2017
Background Genomic methods have proved to be important tools in the analysis of genetic diversity across the range of species and can be used to reveal processes underlying both short- and long-term evolutionary change. This study applied genomic methods

Understanding evolutionary processes during past Quaternary climatic cycles: Can it be applied to the future? [PDF]

, 2010
Climate change affected ecological community make-up during the Quaternary which was probably both the cause of, and was caused by, evolutionary processes such as species evolution, adaptation and extinction of species and ...

The existence of species rests on a metastable equilibrium between inbreeding and outbreeding [PDF]

, 2011
Background: Speciation corresponds to the progressive establishment of reproductive barriers between groups of individuals derived from an ancestral stock.

A genomic tale of inbreeding in western Mediterranean human populations

Human Genetics
Abstract Consanguineous marriages are common in many worldwide human populations, and the biological consequences for offspring can be relevant at the biomedical level. The current genomic revolution displayed through genome-wide studies is challenging the paradigm in the analysis of consanguinity.

Introduced mona monkey Cercopithecus mona is a key predator of bird nests in the endemic‐rich Príncipe Island

Conservation Science and Practice, EarlyView.
Abstract Bird communities in oceanic islands tend to evolve under reduced predation, making them extremely susceptible to introduced predators. Príncipe Island (São Tomé and Príncipe, Central Africa) harbors 11 endemic bird species and eight introduced mammal species.

Potential inbreeding in a small population of a mass flowering species, Xanthorrhoea johnsonii (Xanthorrhoaceae): is your mother my father? [PDF]

, 2012
Xanthorrhoea johnsonii is a long lived slow growing perennial understorey species, that produces a large quantity of passively dispersed seed every 3-5 years. Reproductive maturity is not reached until 20-30 years of age.

Stayability in the Era of Early‐Challenged Females: Genetic Parameters and Correlations With Economically Relevant Traits

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT This study aimed to estimate the variance components, heritabilities and genetic correlations between four new different categories of stayability (STAY48‐2, STAY48‐3, STAY54‐2, STAY54‐3) with weight at 240 days of age (W240), weight at 450 days of age (W450), scrotal circumference at 365 days of age (SC365), age at puberty in males (APM ...
