What Does it Mean to Have "Strong Genes"?

Pregnancy is an exciting time filled with unknowns. Parents wonder what their little one will look like. Will she have mom’s eyes and dad’s penchant for crossword puzzles? Will he look just like mom but have dad’s personality? It’s natural to wonder and explore the possibilities of these kinds of questions, but unfortunately there are no simple answers when predicting. Parents wonder about the concept of strong genes, especially when they consider all the best parts of themselves and imagine how it would be possible to pass those traits along.
