Question

Complete the Punnett Square below for a cross between a red snapdragon (RR) and a white snapdragon (rr). When noting a heterozygous pair, the dominant allele is ALWAYS listed first, (Rr, or Tt).Genotype NOTES: RR - red flowersRr - pink flowersrr - white flowers(4 points) RRrR Rr Rrr rR r

Answer 1

Set up the gametes: parent 1 (RR) → R, R across the top; parent 2 (rr) → r, r down the side.

Punnett square:
- Top row: Rr | Rr
- Bottom row: Rr | Rr

All four offspring are genotype Rr (100%) and phenotype pink flowers (100%).
