The suncoast tree of northwest Africa is known for 2 traits that are said to show simple dominance. The 2 traits are height and
ivann1987 [24]

The genotypes would be bbTT X BbTt

Assuming that bark color is represented by B (b) allele and height is represented by T (t) allele.

Since the traits show simple dominance: blue (B) of dominant over purple (b) and tall (T) is dominant over short (t)

  • The genotype of a tree that is purebred purple (bb) and tall (TT) would be bbTT
  • The genotype of a tree that is heterozygous for both trait would be BbTt
  • Thus, the cross would be bbTT x BbTt
