Summary Introduction
To determine:
The reason why natural selection favor aphids that alternate between asexual and sexual reproduction at different seasons of the year.
Introduction:
Aphids are the tiny sap-sucking insects belong to the superfamily Aphidoidea. These are distributed worldwide, but are commonly found in the temperate region. They have soft bodies which may be black, green, pink and brown in color. They can be alternate between asexual and sexual mode of reproduction within the same host at different seasons of the year.

Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward
