Grew up in a large family with 4 sets of twins, plus other brothers and sisters. The single brothers and sisters, all claimed they would never want to be a twin, us twins, would never have wanted to be a single. Each set of twins, one is dark haired right handed, and the twin, is blonde left handed. And opposites in so many ways. If I lost my twin brother it would be like losing my left arm
Grew up in a large family of 18 children, with 4 sets of twins, myself having a twin brother! All sets were fraternal. Fraternal males , fraternal females and two sets female and male. Even stranger, in each set of twins one twin was dark haired , blue eyed and right handed. The second twin in each set was blonde, brown eyed and left handed!
