Question

1.  Snapdragons can be red (RR), white (WW), or pink (RW).   Cross a red snapdragon with a pink snapdragon.  Give the genotype and phenotype percentages. 

Answer 1

Answer:

RR (hom0zygous dominant) - 50%

RW (heterozygous) - 50%

Red flower - 50 %

Pink flower - 50%

Explanation:

To solve this problem, we need to use a Punnett square. A red snapdragon has a genotype of RR and a pink snapdragon has a genotype of RW.

      R    R

R    RR  RR

W  RW  RW

50% of the offspring would have the RR genotype (hom0zygous dominant) and 50% would have the RW genotype (heterozygous). The RR genotype results in a red flower, and the RW genotype results in a pink flower, so 50% of the offspring would be red and 50% would be pink.
