Sperm from older rats passes on fewer active genes to offspring because of epigenetic changes – The Conversation US
Male rats transfer different hereditary information to their offspring depending on their age.
The Research Brief is a short take about interesting academic work.
The big idea
The sperm of older rats differs from that of younger rats in ways that may affect embryo development, according to recently published research.
Sperm carries not only genes, but also instructions that determine which genes will be turned on or off in offspring. These directions are known as epigenetic information.
In the rats we studied, age had a profound effect on the activity of many genes in sperm. We found age…
