Question

The suncoast tree of northwest Africa is known for 2 traits that are said to show simple dominance. The 2 traits are height and bark color. In height, tall is dominant to short, and in bark color blue is dominant to purple. What would the genotypes be of a suncoast tree that is pure bred purple and tall and a suncoast tree that is heterozygous for both traits?
A. bbTT X BbTt

B. BBtt X BBTT

C. bbtt X bbtt

D. BbTt X BbTt

Answer 1

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
