Ep256 - Evolution of a Strain - Connecting Evolutionary Biology to Selective Breeding

In this continuation of our series The 12 Key Challenges
in Breeding and Creating a Strain, Episode 150 dives
deep into the complexities of establishing a true, purebred
strain—examining the connection and similarities between
evolutionary biology and selective breeding practices. Breeders
striving for perfection face a wide range of challenges, from
genetic issues to environmental influences, and this episode
uncovers the scientific foundations and practical strategies for
overcoming them.


We'll explore the 4 Mechanisms of Evolution identified by Charles
Darwin—variation, inheritance, overproduction of offspring, and
differential survival and reproduction—and how these principles
relate directly to selective breeding. As breeders select for
specific traits, understanding these natural processes is key to
creating a healthy, viable strain over time.


Challenges #6-8 focus on:



Dealing with Epigenetics: The way
environmental factors, such as geography, nutrition, and
management, can influence genetic expression in ways that go
beyond traditional inheritance. We’ll break down how breeders
can harness epigenetic mechanisms for the betterment of their
strains, while managing the effects of undesirable traits.


Gene Flow and Genetic Instability: How the
continuous influx of external genes through practices like
outcrossing and crossbreeding can affect the purity of a
strain. Learn how breeders can manage and even halt gene flow
to avoid genetic dilution and ensure the integrity of their
breed.


Genetic Drift: The unpredictable changes in
genetic composition that occur in small populations. Discover
how breeders can use genetic drift to their advantage,
preserving and enhancing strains during periods of reduced
numbers, while avoiding its pitfalls, such as bottlenecking.



By understanding the science behind selective breeding and the
biological forces that drive evolution, breeders can make
informed decisions that will help them create strong, sustainable
strains.


Whether you're a seasoned breeder or just starting out, this
episode is packed with valuable insights to help you navigate the
challenges of breeding for excellence.


Tune in for a deeper understanding of how
evolutionary biology intersects with breeding practices and how
you can apply this knowledge to your own breeding program. Don't
forget to bring your questions—we’re here to help you grow your
breeding knowledge!


Make sure to follow and watch our future shows.
We plan to dive deep into the world of breeding and genetics,
nutrition and health management, and provide essential tips, so
you too can create high quality strains.  Whether you're
breeding domestic chickens, gamefowl, or various types of
livestock, this show is for you. 


Join us on Bred to Perfection Live, Friday’s at 6pm
PST or 9pm EST on YouTube, as we
discuss the benefits of creating your own strain.


See ya there!

Founder of "The Breeders Academy" 


 We specialize in breeding, and breeding related
topics. This includes proper selection practices and the
use of proven breeding programs. It is our mission to provide our
followers and members a greater understanding of poultry
breeding, poultry genetics, poultry health care and disease
prevention, and how to improve the production and performance
ability of your fowl. 


If you are interested in creating a strain, or improving
your established strain, you are in the right
place. 


We also want to encourage you to join us at the Breeders
Academy, where we will not only help you increase your
knowledge of breeding and advance your skills as a breeder, but
improve the quality and performance of your fowl.
