In a dihybrid cross, a homozygous plant with purple
and axial flowers (PPAA) is crossed with a
homozygous plant with white and top flowers
(ppaa). If the purple flower trait is dominant over
white flowers and axial flowers are dominant over
top flowers, what phenotypic ratio will be produced
in the F1 generation?
purple and axial flowers: white and top
flowers – 3: 1
-
purple and axial: Purple and top: white and
axial: white top – 9: 3: 3: 1
all plants with purple and axial flowers – 4: 0
purple and axial flowers: white and top
