Inheritance In Seeds Question

[Sam_Skunkman]

If a small seeded variety and a large seeded variety are crossed what will the progeny seeds look like?
#1 Somewhere between the two.
#2 Just like the Mom.
#3 Just like the Dad.
#4 Like none of the above.


WHY?
If you do think it makes a difference say why. Mom big or Mom small. Dad, Big or Small
I am not referring to how early or late pollinated, or how many seeds made at one time.
As far as I know seeds size is not dominate or recessive.


I will let folks answer and then I will say what I think is the answer and why. In a few days.

#4
No idea, but I'd guess that seed size is influenced by amount of pollen and time of pollenation/flower development.

imo ...

if you cross A with B .. yes you will probably find some Ab's and Ba's ,, but you might also get something totally unexpected like a X or Y or Z

so i think the answer is .. none of the above

My experience has been the seed will be in the first generation what the mother's family has produced traditionally... into further generations however it will segregate as usual because neither big or small is dominant or particularly beneficial.

I'm not sure I'm smart enough to answer this question but heres a shot in the dark,if the genetics fully intermingle you should end up with mid sized beans.

 

[Tom Hill]

mottling on the other hand both favors survival and is dominant.

 

[stix~]

jajajajajajajaj well a shot in the dark is better than pulling the trigger to early .... i answered and i hadn't understand yet ... i get now that you guys are talking about SEED SIZE ....

heey tom check your PM's ... get at me bro!!-sticky

i havent made enough seeds yet to answer the question ,,, but i've seen seed size difference between sativas and indicas mainly ... could that be it?

 

[Tom Hill]

sam already knew the answer before he asked it hehehhe..

 

[Chimera]

Ask Tina.

 

[Tom Hill]

i would actually lean to small being dominant as like mottling it would seem to be easier for the bird etc to overlook but this does not seem to be the case at at all at least over the short term.. in the long term,, small,, mottled seeds have a better chance for survival and we would think this type of seed will eventually win in regards to surviving..

 

[Tom Hill]

the lessor energy (small) it takes per seed the more individuals an individual can make,, and the more camouflaged (mottled) the better..

 

[Chimera]

Small seeds (shattering) is a wild type trait, overall seed size is a function of multiple loci so it's not so simple as dominant or recessive. See QTL.

I'm not going to ruin the fun, Sam and I have spoken on this topic at depth so I'll keep quiet and let the professor teach the course....

Mottling however is maternal, the achene shell is maternal tissue so it doesn't represent the genotype of the embryo within.

 

[Chimera]

Mottled seed is beneficial in a mixed texture soil, but solid colour soils favour solid coloured seeds. Mottling provides a distraction pattern but that doesn't do so well in single coloured soils where it makes the acenes stand out.

The US army doesn't wear jungle fatigues in the desert and the same holds true for cannabis seed. If you look at enough achenes under a microscope you get a pretty clear idea of the why's and how's of mottling.

 

[Cmobile9]

This is my rational guess... I would have to say that the seed will always take the mom's form.
Because of the formation of bud by mom. I can't imagine dad changing bud formation of the mom that much because of pollen? Total guess though

 

[Tom Hill]

i have never never seen a seeded female plant throw out variable sized seed outside of development stage so there is just no way i am buying the multiple loci bit brother it is not an option, apologies. come school me professor make yourself known to me.

i can surely see mottling being maternal,, i still profess so is seed size... based on experience only differing siblings can produce differing seed size within any given population.. this goes against all we know about multiple loci inheritance which by definition produces variable offpring within and from each individual as the absolute norm..

 

[sourpuss]

Id have to say none of the available answers. Closest id say would be just like mom. But id expect that the seeds would be the size of moms swollen calyxs. I dont think moms origi al seed size dictates her offaprings size. Mom could have been a sativa leaner from a large seed from a indica mother plant. So her seed would have been huge. Her bud structure could be small calyx therefore Id expect her seed would be small.

Sorry just realized like none of the above fits my answer haha

 

[Tom Hill]

Sam?

 

[Midwest sticky]

^^ Sam started this thread knowing the answer lol. And I'm sure you do too. I have no clue so I'm real curious as to what the answer actually is.
End the damn suspense already.

 

[Tom Hill]

for the record,, there is no such thing as a multiple loci trait that magically comes out all the same in the progeny and yes the observation of traits begins with the seed,, i came here for entertainment,, but i am ready to learn

 

[Tom Hill]

it will come out the same as it always does,, they will put their previous beliefs in check and come around to toms reality
