Q for any of you hybridizers......

Well I am very familiar w/ the complexity involved in trying to determine what traits offspring will have. Simple dominance/recessiveness such as Mendel discovered in his pea experiments is often more the exception than the rule. A trait commonly has multiple genes which interact to determine how the trait will be expressed. However sometimes there are "trends" that seem to be followed. For example, w/ cattleya orchids, the color lavender seems to often be dominant -- even over other darker colors. So I'm curious what, if any trends may exist for AVs? For example:

Size-wise, if a mini is crossed with a standard, does the standard tend to dominate?

Color-wise, does dark flower color tend to dominate over a pale one?

Is there a particular color that tends to dominate over most others?

We're learning a bit of hybridizing stuff in another A/V forum I'm on... One of our mods, Jana posted "Dominant & Recessive Traits by Dr. J Smith" Check it out
(You'll have to join the forum to see it, I think--but our forum is free to join and a lotta fun!)

Paul,

You can also post your question on the African violet forum here on Garden Web.

There is usually someone knowledgeable, and it's free to look at and lurk.

Disregard that, I thought I was on the Maine forum.

If you google jeff smith african violets, you'll come up with a number of links to AV genetic traits. I've linked a good one here. Dr. Jeff Smith writes an article for the AVSA magazine in reference to hybridizing AV's and talks about the genetics.

Hope this helps,
Elaine

Thanks folks! Checked out the "Jeff Smith" link -- that was very cool! Just the type of stuff I was looking for. Some of the traits that turned out to be dominant or recessive rather suprised me -- I guess because of the only AV's I usually see. [For instance I don't commonly see the "Fantasy" types & so would have assumed that trait to be recessive]
