Ep104 - Epigenetics: How the Environment influences Genetic Inheritance

There is a lot of confusion in this area of
breeding. So much so, that many breeders are not able to
produce high quality strains. They purchase birds from a
reputable breeder, and are confused when the fowl they produce
are not like the original breeder’s fowl.


We’ve all seen it, strains change when they’re moved to
different locations. The question is, are these changes
temporary or permanent? And, what can we do about it? The
environment can have a direct effect on the phenotype of your
strain. For example, the weather can turn from hot to cold, or
cold to hot, and go from dry to wet, and nutrition can affect
growth and development, disease can weaken the strain and kill
important individuals, and poor management can cause disease and
stress. But, none of these factors will have a direct effect on
the strains genotype.


This is an important concept, and has an effect
on your selection and the improvement of your strains. For
example, if we are not seeing their true value and potential, due
to a poor environment, this prevents us from selecting properly.
They may appear “better or worse” than their true genetic value,
depending on whether they receive a favorable or unfavorable
environment. This is especially true when it comes to their form,
function or beauty.
