A new preprint by Hilde Schneeman and John Welch using FGM to explore what we can infer from introgression line data. Quite a lot of overdominance in the reanalysed datasets, but it may well be transient (background dependent) and thus fixable. Again, an important read for anyone interested in hybridization. #PopGen #Hybridization

Awesome field trip last week with members of the Wessinger lab to collect samples for a project on hybridization and introgression in Penstemon. The high deserts on the edge of the Mojave and the Great Basin are an amazing place to visit. #Penstemon #FieldWork #Hybridization #Evolution #Phenotype

#Hybridization and #introgression can boost #speciation, but hybridization may also cause loss of #biodiversity - how do species avoid this “dark side of introgression”? Discuss with us @m_matschiner in our symposium no.3 at #SMBE2023 in sunny Italy! https://www.smbe2023.org/

"The most reported #alien #abduction experience is the 'alien grey' abduction. During these abductions, degenerate looking humans with large black eyes steal human genetic material, insert implants and even attempt to create a 'hybrid species' using their genetics and humanity's.

While many perceive these contacts to be #extraterrestrial, due to the advanced technology and unusual appearance, it is also possible that these beings are degenerated human beings that are seeking to heal their deformities by harvesting #DNA from a time before their fall, or from an era of the human form that is not degraded. The use of genetic splicing, or #hybridization, is thus an attempt to insert themselves into our evolutionary stream. Why? Because they have failed at their own and are not interested in taking #spiritual #responsibility for that failure.

Strangely, the ' #alien ' #greys have the same culture as the #technocratic #transhumanist ' #elite ' who also seek to use #implants to monitor and track humans. Certain elite groups also obsess over #eugenics, #GeneticEngineering and the creation of #golems, or empty vessels. The activities and culture of he grey 'aliens' is the culture of the #technocratic elite."

New study on effects of global warming on interspecific hybridization: oxidative cost in hybrids of crested newts

With RADseq data, how does one differentiate shared ancestral polymorphism from backcross hybridization in two closely related sympatric species?

@DavidLowry Looks like a great study!

A new paper based on Paul Thompson's 1978 dissertation on the Quercus prinoides complex (the chinquapin oaks), describing two hybrids involving Q. prinoides / Q. muehlenbergii. This is a tough group... there is still ample need in North America for taxonomic discovery, documentation of variation within species, and clarification of the effects of hybridization on the species we recognize.

I'm looking for the first use of the phrase "introgressive hybridization". So far, this is the earliest I've found:
Anderson, E., & Hubricht, L. (1938). Hybridization in Tradescantia. III. The evidence for introgressive hybridization. American Journal of Botany, 396-402.

It’s beginning to look a lot like… a brand new evolution experiment happening in the lab! ✨✨✨#yeast #Saccharomyces #ExperimentalEvolution #Hybridization

I am ecophysiologist, with a focus on the effect of various environmental factors on the oxidative status of ectotherms. Special interest on amphibians and their ability to adapt to environmental changes, but I also examine the oxidative costs of interspecific hybridization.
