Flower diameter in sunflowers is a quantitative trait. a plant with 6-cm flowers, from a highly inbred strain, is crossed to a plant with 30-cm flowers, also from a highly inbred strain. the f1 have 18-cm flowers. f1 × f1 crosses yield f2 plants with flowers ranging from 6 to 30 cm in diameter, in approximately 4-cm intervals (6, 10, 14, 18, 22, 26, 30). an 18-cm f1 plant is crossed to a 6-cm plant. what is the probability of an offspring with one additive allele, if all genes that influence this trait are unlinked?

a. 1/3
b. 1/4
c. 1/6
d. 3/8
e. 1/16

c. movement because i took the test and it lets me review my answers

correct answer: understand the different control methods available

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.
