Want to learn more about the topic in this week’s video? Here are some keywords/phrases to get your googling started:

epigenetics: genetic control by factors other than an individual’s DNA sequence

epigenetic inheritance: transmittance of information from one generation of an organism to the next that affects the traits of offspring without altering the DNA sequence
