So I guess that's a 'yes, probably'

The maternal inheritance of  plastid and mitochondria genetics basically

But control of these  rests with nuclear DNA for most part. So  how well
the potential of maternal  inheritance is able to perform is partially
dependent on proper control signals from nucleus. Sort of like you can
have a super winning race car, but  you also need a good driver to get

There is also methylation and gene silencing  of either maternal
silencing or paternal silencing, controlling which parent gene works.

So anything  dependent  on chlorophyll or energy production will be
biased to  pod parent. This can have more of an influence on plant
hardiness, speed of growth and flower stalk thickness etc.

In your experience (or what you've heard from others), does maternal
influence skew the distribution towards that of the pod parent?
