Sometimes it skips a generation, myself, I look the spitting image of my grandmother, and nothing like my mother.
Indeed, our great niece looks very much like my wife's sister, her grandmother, except in coloration. Grandma was a blue eyed blonde girl, and not much older than great niece is now when I first met her. (12 verses 10). But grandma had a "thing" with a "Mexican" fellow (her second husband, although not so for long) and her grandaughters have dusky complections and the younger one who looks like her otherwise has a mass of dark black beautiful hair, and dark eyes.
OTOH, for some reason, my brother's son was the spitting image of me from about age 8 to 14 or 15. Not so much anymore, although there is of course still quite a bit of resemblance.
