Genetic draft, selective interference, and population genetics of rapid adaptation [PDF]
, 2013 To learn about the past from a sample of genomic sequences, one needs to understand how evolutionary processes shape genetic diversity. Most population genetic inference is based on frameworks assuming adaptive evolution is rare.

Outcrossing Rate and Genetic Variability in Mexican Race Avocado
Journal of the American Society for Horticultural Science, 2019 The blooming behavior of the avocado Persea americana Mill. is a sophisticated mechanism that prevents effective self-pollination, enables close pollination, and encourages cross-pollination.

The scale of population structure in Arabidopsis thaliana [PDF]
, 2010 The population structure of an organism reflects its evolutionary history and influences its evolutionary trajectory. It constrains the combination of genetic diversity and reveals patterns of past gene flow.

Evaluation of the risks of contaminating low erucic acid rapeseed with high erucic rapeseed and identification of mitigation strategies [PDF]
, 2019 High erucic acid rapeseed (HEAR) oil is under increasing demand for various industrial applications. However, many growers are concerned that if they grow the crop, they will not be able to revert to other rapeseed varieties in the future due to the risk

Yeast Sex: Surprisingly High Rates of Outcrossing between Asci
PLoS ONE, 2010 Saccharomyces yeasts are an important model system in many areas of biological research. Very little is known about their ecology and evolution in the wild, but interest in this natural history is growing. Extensive work with lab strains in the last century uncovered the Saccharomyces life cycle.

Molecular evidence of outcrossing rate variability in Brassica napus [PDF]
Euphytica, 2011 A leafy crop of Brassica napus L. called nabicol has been grown by farmers in northwestern Spain for many years, being an important horticultural product during the winter season. A collection of landraces of a Brassica napus leafy crop called nabicol is kept at 'Misión Biológica de Galicia' (CSIC-Spain) which can be used to search for desirable ...

Mating system parameters in a high density population of andirobas in the Amazon forest
Pesquisa Agropecuária Brasileira, 2013 The objective of this work was to estimate the mating system parameters of a andiroba (Carapa guianensis) population using microsatellite markers and the mixed and correlated mating models.
