A "cutting-edge" plant breeder wants to create roses with fuzzy leaves. He crosses an azalea, which is heterozygous for fuzzy leaves, with a rose that is homozygous for flat leaves. (we are pretending that the azalea and the rose can produce offspring). H = fuzzy leaves (dominant) h = flat leaves (recessive) what is the genotype of the fuzzy-leafed offspring of this cross?

H = fuzzy leaves (dominant)

h = flat leaves (recessive)

Genotype of Azalea heterozygous for fuzzy leaves = Hh

Genotype rose homozygous for flat leaves = hh

If we cross Azalea and rose

Hh  x  hh

F1: Hh Hh hh hh

The genotype of the fuzzy-leafed offspring is Hh.
