Do you mention in an episode how a child contains the full genetic markup of both parents? And that a child can express different genes at different parts of life?

Yes, the concept that a child contains the complete genetic material from both parents and can express different genes at different stages of life is discussed on the Huberman Lab, specifically in an episode featuring Oded Rechavi.

Andrew Huberman and Oded Rechavi explain that each cell in a human body contains two copies of every chromosome, one from each parent. These are called alleles and represent different versions of the same gene. They delve into a phenomenon known as imprinting, where certain genes are expressed depending on whether they are inherited from the mother or father. This mechanism can change throughout an individual's life. For instance, certain cells might express maternal genes early in life and switch to paternal genes later on 1.

Additionally, they mention that while genetic traits can be inherited and expressed based on parental lineage, these expressions can change over time, illustrating how a child might show characteristics attributed to one parent at one life stage and to the other parent at another stage 1.
