suppose that white carnations are INCOMPLETE dominant over red thorns are COMPLETELY dominant over smooth stemmed flowers.
A carnation with both color alleles will be pink.
Pollonate a red thornless carnation with the pollen from the anther of another that is white and pure for thorns.
Use the symbols R/r for color and T/t for thorns.
take it through the F1 phase only?
how many genotypes are there in F1?
what are the phenotypes?
thank you very much an advance!!!!
Incomplete dominance?
RR=white; Rr=pink; rr=white
T= thorns; t = thornless
Red, thornless x white, homozygous thorned
P: rrtt x RRTT
gametes from first parent: rt rt rt rt
gametes from second parent RT RT RT RT
F1: all rRtT
1. Only one genotype in the F1 because each parent only gave one type of gamete.
2. F1 is all rRtT which is pink, thorned
