Answer: option B) 0.25
Explanation:
Total population of four o’clock flowers = 8
Number of red flowers with RR phenotype = 5
Number of pink flowers with Rr phenotype = 2
Number of white flower with rr phenotype = 1
To obtain the phenotype frequency of plants with pink flowers:
put the number or Rr phenotype OVER the total population of four o'clock plants
i.e 2/8
= 0.25
Therefore, 0.25 is the answer
Phenotype is how the offspring will look like (the observable characteristics of it). the genotype is make up of the genes responsible for a trait
