An tetraploid plant undergoes self-fertilization. At least two dominant A alleles are needed to obtain the dominant phenotype. At what frequency will progeny with the dominant phenotype appear?

The frequency will be  35/36

Explanation:

An tetraploid plant will only produce a gamete which will be Aa, but during a self crossing a progeny with genotype will be produced and this will happen at a frequency of 35/36 and this simply means that the progenies produced during the self crossing  will all have a dominant phenotype

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.
