Assessing aggregate exposure to a series of compounds with the same biological mechanism is called cumulative exposure assessment.
<h3>
What is cumulative exposure?</h3>
Because cumulative exposure evaluations evaluate exposure to numerous stressors via different pathways, they are referred to as "combined exposure assessments." Exposures to a single stressor are estimated using aggregate evaluations from different sources and pathways.
Cumulative evaluations portray real-world exposure more accurately, but they also provide an element of complexity not seen in typical exposure assessments , which evaluate stressors separately.

Answer:
a) The expected phenotype of the F1 plants is 100% RrBb, red kernels.
b) The expected phenotypic classes in the F2 are: 9:3:3:1
9/16 R-B-, 3/16 rrB-, 3/16 R-bb, 1/16 rrbb
Proportions 9:6:1.
9/16 Red kernel (R-B-), 6/16 Brown kernel (rrB- + R-bb), 1/16 White kernel (rrbb)
