Correlate crossing-over with genetic linkage

The closer together different genetic sequences are in the same chromosome the smaller is the chance of crossing-over/recombination among them

Explanation:

Genetic linkage refers to genetic sequences which are located on the same chromosome, and thereby they are usually inherited together during meiosis. On the other hand, crossing over (also known as recombination) refers to the exchange of chromosome fragments between non-sister chromatids during meiosis. In consequence, the closer together two genetic sequences are on the same chromosome, the lesser will be the chance they will be separated by crossing-over.

i think the answer is b.

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.
