This special SDB ice pink is the
product of years of breeding and, of course, divine intervention. Last night
while I was sleeping the skies opened up and miraculously turned this early bird
into an ice pink. Note the exceptional cold tolerance of this seedling. If this
is not proof intelligent design then I do not know what is. I think I will
release this little miracle for use in Barrow Alaska--call it PINK ICE
On a more serious note, this
seedling is an F1 derived from the cross (Infanta x Girl Pixie). Where Infanta
is a light orange glaciata and Girl Pixie is pink. We know from this F1 that the
genotype of Infanta is heterozygous TTtt, and homozygous oooo where T promotes
the conversion of lycopene into beta-carotene and ?o? blocks the conversion of
orange beta-carotene into yellow zeaxanthin. It is quite possible that Infanta?s
TTtt genotype reduces its concentration of beta-carotene thus producing its
light orange appearance.
Girl Pixie is pink and carries
the tttt genotype.
