Hi Judy,  The grandmother effect was covered in one of my graduate
nutrition courses.  Reading the research on the grandmother effect made a
big impact on me.  Since I've just moved (my notes are still packed), and
my nutrition professor has died, I'm going to have to just paraphrase from
memory (or do a literature search, which I may do).  Anyway, it goes like
this:  nutritionists have noticed that malnutrition during a woman's
pregnancy seems to affect the daughter's ability to nourish her fetus,
resulting in smaller grandchildren, or other changes.  Obviously it would
be immoral to experiment on humans, and longitudinal studies based on
self-selected diets of specific individuals are difficult in that the
period of elapsed time is so long, so nutrition researchers designed animal
studies to see if they could measure a physiological effect.  Sure enough,
in animal studies the placenta in the daughter is measurably affected in
its ability to deliver a variety of nutrients, when she herself was
deprived in utero.  This is exciting in that it gives weight to the
observations of human nutritionists in the field, and rise to the term,
"grandmother effect."
