Peyton Byrd · Answer 1

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
