Answer to did aphids acquire their ability to make carotenoids through horizontal gene transfer carotenoids are colored.
The four disparate images shown in figure 1 have this in common: each represents a radical adaptation that would not have happened had lateral gene transfer (lgt), also known as horizontal gene transfer (hgt), not been the powerful evolutionary force we now know it to be. Perspectives on the phylogenetic tree horizontal gene transfer is the transfer of genes between aphids are insects that vary in color based on carotenoid.

Horizontal gene transfer (hgt) or lateral gene transfer (lgt) is the movement of genetic material between unicellular and/or multicellular organisms other than by the (vertical) transmission of dna from parent to offspring hgt is an important factor in the evolution of many organisms. Aphids come in different colors, a critical issue when fate is a question of pigmentation: red aphids tend to be consumed by ladybugs and green ones by parasitic wasps.

Horizontal gene transfer was partly responsible for reproductively isolating lab-bred populations of fruit flies from wild ones – a major step on the way towards speciation still, most biologists viewed horizontal gene transfer among insects and other animals as something of an anomaly yes, bacteria and viruses exchanged dna on a daily basis. Horizontal gene transfer, or the process of swapping genetic material between neighboring “contemporary” bacteria, is another means by.
