I believe that yellow may be recessive,but it is certainly co-linked with red to produce orange,which seems to be the dominant color in my 25 years of breeding Hippeastrum.Years ago I selfed Pasadena, a tetraploid double hybrid,having red with white stripes coloration. The majority of the seedlings were reddish orange or orange. Del--- On Mon, 4/12/10, J.E. Shields <jshields@indy.net> wrote: From: J.E.

The peaches are recessive as well, although I'm not sure we would pick up a partial penetrance of the peach mutation just by eyeball.
