Genomic imprinting studies (Burt & Trivers, 2006) suggests that dental enamel is a contribution from paternal imprinted genes that are also associated with greater striatal and hypothalamic development, muscular development, and, sometimes, brown fat deposits.
Those same genes are also associated, in mice, with pup retrieval, nest building, and nursing - all behaviors that reflect paternal influence on daughters.
