    Where Does Elsie's Hair Color Come From? A "De-Simplified" Pedigree Lesson
    Pedigree analysis is part of most Genetics curricula, but the examples traditionally used in genetics courses present phenotypes as if they were entirely and inexorably defined by genotype. This does not reflect the current state of understanding...
