Answer:
Four (4)
Explanation:
Assuming that the R (red petal) allele is dominant over the r (pink petal) allele and the T (tall bush) allele is dominant over the t (short bush) allele:
R_T_ = Red petal with tall bush
R_tt = Red petal with short bush
rrT_ = Pink petal with tall bush
rrtt = Pink petal with short bush
From the resulting offspring:
Total number of R_T_ = 9
Total number of R_tt = 3
Total number of rrT_ = 3
Total number of rrtt = 1
Hence, four (4) phenotype variations are possible with their respective proportion shown above.
