Re: Questions, Questions and more Questions
I would say that 50% comes from the male and 50% comes from the female.
But that does not mean it show up that way in your pumpkin. e.g. lets say
your pumpkin plant is Rr(geno type) for roundness Big R meaning round and
little r meaning long or not so round, that means your pumpkin will be
round. Now back to the 50-50 thing it still gets half of its genetic info
from each parent, but in the pheno type(the pumpkin) you dont see the recessive
trait.
A extreme example of that would be if your take a plant that is homozygous(spell?)
recessive in every trait and cross it with one that is homozygous dominate,
the product of this cross would appear to be a 'clone' of the dominate
one. But it would still be 50% form mom and 50% from dad, even though all
of the visible characteristics only point to one parent.
I hope this helps, this is pretty basic you still have to consider what
kind of cross it is, just a simple Dominate a single trait shown, or Co-dominate
like spotted cows both colors show up, or In-complete dominate like red
and white flowers make pink ones.
P.S. I have found that there is very little info out there on pumpkin
genetics, even if there was I dont thing the average grower would have
enough time or money to have a lab study pumpkin DNA or years trying to
purify a trait or group of traits.
