If a population of four o’clock flowers consists of five rr plants (red flowers), two rr plants (pink flowers), and one rr plant (white flowers), the phenotype frequency of plants with pink flowers is:

a) 0.125. b) 0.25. c) 0.5. d) 0.75.

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

hi there!

answer: b. nucleolus

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
