Phenotype is Pink and tall snapdragon

Explanation:

Given

Tallness ( T) is dominant to dwarfness (t)

Red (R) flower color is dominant to white (r)

It is given that heterozygous condition results in pink (Rr) flower color which means that the allels for color of flower show co dominance

Genotype of dwarf red snapdragon is RRtt

Genotype of a plant homozygous for tallness and white flowers is rrTT

The punnet square representing the cross between RRtt and rrTT is as given below-

Rt Rt Rt Rt

rT RrTt RrTt RrTt RrTt

Thus all the offspring have genotype RrTt

Phenotype is Pink and tall snapdragon
