The ability to touch your nose with the tip of your tongue is a dominant genetic trait. And red hair
shows incomplete dominance with blonde hair, with the heterozygous phenotype being
strawberry blonde.
A woman with strawberry blonde hair who is able to touch her nose with her tongue (but her
mother could not) is married to a man whose mother had red hair and his father had blonde hair,
and he is heterozygous for nose-touching ability.
