Step-by-step explanation:
In snapdragons, the color of the flower is controlled by incomplete dominance. The two alleles are red (R) and white (W). This means that the petals can be red (RR), white (WW), or pink (RW).
Now, if two pink flowers are crossed, we get the following Punnett Square:
We can see in the Punnett square that:
- one out of four (1/4) of the offspring has the genotype RR and so has a red-flowered phenotype. That is: 25% of the offspring has the genotype RR and so has a red-flowered phenotype.
-one out of four (1/4) of the offspring has the genotype WW and so a white-flowered phenotype. That is: 25% of the offspring has the genotype WW and so a white-flowered phenotype
-two out of the four offspring produced in this cross have the heterozygous genotype RW and so have a pink-flowered phenotype. That is: 50% in this cross will have the heterozygous genotype RW and so have a pink-flowered phenotype.
We can conclude that the correct answer is:
Answer:Punnett square:Probabilities:25% of the offspring has the genotype RR and so has a red-flowered phenotype. 25% of the offspring has the genotype WW and so a white-flowered phenotype.50% in this cross will have the heterozygous genotype RW and so have a pink-flowered phenotype.
