For instance, these hamsters breed only in the late spring and early summer, when the days are longest. This is for them to prevent giving birth in resource-scarce winter months. The study mainly focuses on decreasing DNA methylation, a methyl group. This will shut down the hamster’s reproductive competency because of the decreased DNA methylation.
