I'm an English major, not a scientist, but genetics has always fascinated me. It's always interesting to compare family members to see who looks like whom, and what traits have been carried over through the generations.
My husband had never seen a photo of his great-grandfather until very recently. Their resemblance was striking. He always wondered whom in the family he resembled, since he doesn't look a lot like either of his parents. However, when he saw the picture of his great-grandfather, his question was answered.
It is my hope that further genetic studies and gene therapy can help eradicate diseases like cancer and Alzheimer’s.
