Western Honey Bee Epigenetics

APBIO-2EVHVF

The contrast in the development and social behavior of the western honey bee, Apis mellifera, has been shown to depend on whether bee larvae are fed royal jelly or not.

Those larvae fed jelly will accelerate growth and become queens; all others are destined to become drones. The drastically different developmental outcomes occur despite equivalent genomes, suggesting an epigenetic mechanism.

Which of the following choices would be a feasible mechanism to investigate?

A

Recombination of genomic DNA, leading to the loss and expression of relevant genes.

B

Post-translation modification, leading to altered function of the proteins involved in development.

C

Methylation of histone proteins or genomic DNA, resulting in the silencing of genes.

D

Examining the jelly for genetic material that when incorporated into the larvae promote the royal pathway.
