Heredity Podcast

In this episode we explore the nature vs. nurture debate in one of humanities closest companions – Dogs! Why do they do the things they do? Are their behaviours hardwired into their DNA? Tune in and listen to Dr Juliane Friedrich, Dr Pamela Wiener and Dr Marie Haskell as they discuss complex genetic behaviour traits in German shepherd dogs, collaborating with the Swedish Armed Forces, and how thei...

The annual Population Genetics Group Forum is an important, and much beloved, conference in the fields of genetics and evolution. As registration opens for the 53 meeting of PopGroup (to be held at the University of Leicester, 5th – 8th January 2020), we hear what's in-store from three of the people organising it: Dr Rob Hammond, Dr Richard Badge and PhD student Max John. We then delve into the hi...

Fish farming, or aquaculture, is an important source of animal protein, particularly in developing nations. Unfortunately, aquaculture is highly susceptible to outbreaks of infectious disease. In this episode, Lior David and Roni Tadmor-Levi (The Hebrew University of Jerusalem) discuss their work trying to identify the genetic basis of disease survival in the common carp (Cyprinus carpio) when cha...

An essential aspect of life is reproduction, and an essential aspect of reproduction is sex... except when it isn't. While common in invertebrates, asexual reproduction is only seen in around 90 vertebrate species. And in this episode, Dr Susana Freitas (University of Lausanne, Switzerland) explains her work looking at the hybrid origin of parthenogenesis in what may be the best-studied asexual ve...

Species are often thought of as discreet and separate from one another. However, hybrid zones often form between closely related species, providing the opportunity to test many evolutionary hypotheses. In this episode, we talk to Dr Henrique Batalha-Filho (Universidade Federal da Bahia, Brazil) and Dr Marcos Maldonado-Coelho (Lund University, Sweden) about their work characterising a hybrid zone b...

The Faroe Islands are a North Atlantic archipelago, famed for being a Viking stronghold. However, for the past few centuries the islands have themselves been besieged by one of the world's greatest invaders: the brown rat. In this episode, Dr Emily Puckett (University of Memphis) and Dr Eyðfinn Magnussen (University of the Faroe Islands) discuss their recent paper looking at the current and histor...

How do you breed a high-production cow fit for a changing world? It's rare that we discuss the impact of climate change on cattle agriculture, yet it's important to consider how rising temperatures will impact this important part of the global food chain. In today's episode, Prof. Ismo Strandén, Prof. Juha Kantanen and Prof. Michael Bruford discuss a simulation-based approach for identifying optim...

Collaboration is an essential aspect of modern science, and the authors featured in today's episode epitomise this relationship. In our most ambitions interview to date, all four first authors of a recent Heredity paper come together to discuss their work looking at range expansions in the blacktip reef shark (Carcharhinus melanopterus). Their results provide a cautionary tale for researchers inte...

Some like it hot. Some like it cold. But whatever an organism's preference, our changing climate is likely going to force them to adapt to new temperature regimes. This raises a particularly interesting question for those species with complex life-cycles: do different life stages respond to thermal pressures in a similar way? Or do they display distinct evolutionary trends? In this episode we spea...

Storytelling facilitated both the emergence of the scientific discipline and the evolution of human intelligence. At least, that's what Prof. Enrico Coen argues. A former President of the genetics society, Prof. Coen, from the John Innes Centre, has two articles in the recent Heredity Special issue commemorating 100 years of The Genetics Society. In the first, he creatively recounts the rise of Ho...

We tend to think of science as objective, but as with any human endeavour it is fraught with biases: cognitive, technical, personal and cultural. Interestingly, it turns out that inheritance can also be biased, with the transmission of genes often displaying anything but 'fair' segregation. As the Genetics Society celebrates its centenary, join president Prof. Laurence Hurst as he discusses 100 ye...

Why do the tropics contain such a diversity of life? In this episode, we explore this question with Matt Orton and Prof. Sarah Adamowicz from the University of Guelph. Listen to them discuss their recent research paper – Is molecular evolution faster in the tropics? – and hear about the challenge it poses to the long standing Evolutionary Speed Hypothesis. Hosted on Acast. See acast.com/privacy fo...

In this episode we explore the genetic structuring of orchids in the cloud rainforests of Ecuador. While we mainly think of orchids as ornamental houseplants, many wild species are vulnerable to poaching or deforestation. In a recent Heredity paper, Professor José Iriondo (King Juan Carlos University, Madrid) and colleagues investigated the fine-scale genetic structure of an unassuming orchid in a...

From the days of Darwin and Mendel, studies on colouration have played a vital role in deciphering the mechanisms of natural selection and genetic heredity. While this work has encompassed many species from all branches of the tree of life, a particularly noteworthy one is the incredibly colour diverse grove snail, Cepaea nemoralis. In this special double-whammy episode, we discuss two recent Here...

Animal colouration is fascinating! Conspicuously affected by natural selection, an animal's colour pattern can impact many aspects of its life: from how well it can attract a mate to its success at avoiding predation. Of course, they can also be incredibly beautiful. In this episode, we hear from Dr Jake Morris (University College London – UCL) about his recent research investigating the genetic b...

How repeatable is evolution? This is one of the biggest questions in modern day biology, and until recently it seemed unanswerable. However, the growing number of known cases of parallel evolution—where two closely related organisms adapt to an environment in the same way—is revealing just how predictable evolution can be. In this episode, Dr Allie Graham (Oregon State University) and Dr Kevin McC...

A fascinating mosaic has recently been discovered in the Mediterranean, and we're not talking about the famous tiled art. Here, we're talking about a genetic mosaic in the Mediterranean mussel (Mytilus galloprovincialis), which stretches for over 600 km along the North African coast. What led to this incredibly large hybrid zone? Dr Nicolas Bierne from the University of Montpellier explains all in...

When we think of Charles Darwin and his theory of natural selection, the mind conjures images of exotic voyages to distant lands. However, in reality, Darwin's theory was more heavily influenced by his observations on the process of domestication, which he made in his own backyard. The evolution of domestic animals still fascinates biologists, and in this episode of the Heredity Podcast Dr Amir Fa...

While there is little doubt that the grey wolf is one of the world's most iconic species, it is equally true that it is one of the world's most reviled. This later sentiment has seen them extirpated from much of their former habitat. However, in a few places, wolves are making a comeback. In this episode, Sarah Hendricks, Dr Rena M. Schweizer and Prof. Robert Wayne discuss their recent research ex...

Every winter, geneticists from around the world brave the unpredictable weather to gather for the annual Population Genetics Group Conference. This year, Oxford Brookes University played host to the 52nd such meeting, and with a delegate list of almost 250 researchers, a programme of 106 talks, and around 41 posters, it proved to be a three day celebration of the latest and greatest research in th...

With their delicate, trumpet shaped flowers that open to greet the rising sun, the morning glory has long been a horticultural favourite. Unfortunately, the quick growth and hardy nature of these plants has made them a noxious invasive weed in many parts of the world, with particularly damaging impacts on crop agriculture. Here, Dr Diego Alvarado Serrano, from the University of Michigan, discusses...

Southern right whales have had a rough few centuries, being brought to the brink of oblivion more than once by the whaling industry. Before that, climatic shifts likely played havoc with their coastal breeding grounds. What impact did these events have on their population genetics and connectivity? These are the questions being tackled by Dr Emma Carroll and Prof. Oscar Gaggiotti. Join them as the...

What makes a beetle red? Or metallic? Or striped? And why display such a diversity of colour patterns within one species? These are the questions being asked by Lynette Strickland, a PhD candidate at the University of Illinois at Urbana-Champaign and a Pre-doctoral fellow at the Smithsonian Tropical Research Institute. Join us as we discuss her recent research on the genetic and ecological basis o...

Europe's 102 million domestic cats were spread across the continent by the Roman Empire. At least, that was the consensus. However, new genetic, archaeological, and archaeozoological evidence suggests that our feline friends were present in Central Europe thousands of years earlier than previously thought. How did they get there? And what does this mean for our understanding of cat domestication?...

In this episode we explore a hybrid approach for genotyping one of the most variable parts of the vertebrate genome: the major histocompatibility complex (MHC). Join Dr Silvia Fuselli (University of Ferrara) and Dr Rodrigo Baptista (University of Georgia) as they explain their work combining the best aspects of both next and third generation sequencing platforms—an approach that is bringing us eve...
