OK, haven't been drinking, but been thinking.
Now, since I'm not a genetic guru, I have a few questions that I'd like some input on.
How much of the offspring is dictated by the male? My theory, and info tells me, that this is dictated by the time of day, pollination takes place.
If you pollinate at the time the female opens,(say 6:00 A.M) then 50% (a good number) of the male genetics will pass on to the Offspring.
If you pollinate at (Again only a reference) 9:00 AM or close to the end of the Female flowers receptiveness, then the offspring will have 75 % female genes and 25% male.
I think all remakes are lacking one major element, and that is time of Pollination.
Again only thinking out loud, But why are there so many differences in same cross seeds, ie: 842 Eaton , and the 845 Nesbitt. Same cross, but 842 Eaton has more 723 Genetics show in the offspring, and the 845 Nesbitt has 846 Calai genes leading the way.
So to be more Exact on crosses do we need to record the pollination time?

Interesting! This would be a worthwhile study if in fact, time matters.

I think no matter when you pollinate a flower. You will have
the same number of genetic modifers being ressive or dominate come togeather during the gamet stage. Even so pumpkins on
the same vine are all sisters and all diffrent just as male
flowers from the same vine are all brothers you will most likely get better consistancy useing only one male but a better seed count useing more than one. The genetic game can
be a pain!

50% of the genetic information comes from the female (egg), 50% comes from the male (sprem-pollen grain-. Time of pollination does not affect this at all.

Gordon is right. This is fundamental genetics. Always 50:50 split. No effect from pollination time, phase of the moon or anything else. There will always be a wide variety of offspring in the same genetic cross. One of my kids has wavy hair, the other two have straight....etc etc

The genetic traits are always split in "half" during zygote (seed) formation. Half the traits of the pumpkin will come from the male, half from the female. But weather or not the genes (aleles) are dominate or recesive is dictated by weather or not the cross is homozygous dominate / recesive (TT,tt) or heterozygous Tt for a specific trait.

One thing everyone over looks when talking AG genetics is that we are unually crossing something that has been crossed for several generations. So there will be multiple outcomes of offspring. Only by creating "inbreds" by selfing for multiple generations and THEN crossing two inbreds will we get consistant "hybrids" that have the same characteristics.

Have growers been doing this? If not then of course lets start.....

I've already begun research experiments with my Prizewinners regarding selfing and genetic traits. I will probably incorporate AG's into the research project next year.
