Inbreeding depression and segregation distortion in Chinook salmon: Conservation implications of genetic load
Strong evidence that shows inbreeding in many plants and animals can lead to detrimental effects at the level of the organism as well as the population. Inbreeding and its effects have been the focus of much attention in terms of conservation and captive rearing and breeding programs for many …

Phenotypic and transcriptomic approaches to understanding natural dicamba tolerance in soybean, and an exploration of segregation distortion in SCN resistance
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2026-12-01

Investigating the effects of genetic variation on heterochromatic crossover events in Arabidopsis thaliana
… to heterochromatic crossover frequency and segregation distortion within hybrid populations was identified. Heterochromatic crossover variation was likely due to both *cis*- and *trans*-acting factors. The effect of disease on genome-wide crossover frequency was explored and results from …

Genetics Analysis of Standing Variation for Floral Morphology and Fitness Components in a Natural Population of Mimulus Guttatus (Common Monkeyflower)
… flowering time, and leaf size. We also mapped segregation distortion loci and QTLs for fertility components (pollen viability and seed set) that exhibit inbreeding depression. We compare the genetic architecture of these two sets of traits and find clear differences. Morphological traits and …

Simple Sequence Repeat Development, Polymorphism and Genetic Mapping in Quinoa (Chenopodium quinoa Willd.)
… spanning a total of 606 cM. A high level of segregation distortion was observed in both populations, indicating possible chromosomal regions associated with gametophytic factors or QTLs conferring a selective advantage under the particular growing conditions. As these maps are based primarily …

Inheritance and expression of Cry3Aa and PVY-O coat protein transgenes in diploid and tetraploid potato
The potential benefits of plant genetic engineering for disease and pest resistance have been widely acknowledged in many studies, and although genetically modified crops are still encountering public wariness, these benefits warrant continued exploration. Because of its intrinsic economic …

Bulk segregant analysis for anther culture response and leptine content in backcross families of diploid potato
… <I>S. chacoense</I>, were used to examine the segregation of microsatellite markers and three traits in backcrosses. Two of the traits, anther culture competence and 2<I>n</I> pollen production, originated from <I>S. phureja</I> whereas the third, leptine production (a specific glycoalkaloid …
