What is the Origin of Transgenerational Phenotypes?

This concept is a central focus of modern epigenetics and developmental endocrinology, challenging the long-held dogma of strict genetic inheritance. The initial evidence came from studies showing that transient exposure to endocrine-disrupting compounds in one generation could lead to disease in unexposed later generations.

What is the Mechanism of Transgenerational Phenotypes?

The inheritance is mediated by stable epigenetic marks established in the germline of the exposed generation, most notably through alterations in DNA methylation patterns or the presence of specific non-coding RNAs within the sperm or oocyte. These epigenetic modifications survive the two major waves of global reprogramming in the zygote and embryo, allowing the altered gene expression pattern to be transmitted to future, unexposed offspring.

Transgenerational Phenotypes

Meaning

Transgenerational Phenotypes are heritable biological traits, disease predispositions, or altered physiological states that are observed in subsequent generations without the direct presence of the initial environmental exposure or any change to the primary DNA sequence. This inheritance pattern bypasses the traditional Mendelian laws and extends the impact of parental environment to grandchildren and beyond.
