With the growing numbers of gay fathers in our society, research suggests that they are likely to divide the work involved in child care
relatively evenly and that they are happy with their couple relationships, and that gay
men make perfectly
fit parents.
«All else being equal, a woman who conceived children with
men who possessed high fitness genes (e.g.,
relatively free of deleterious genetic mutations) probably had children who were more likely to survive and later reproduce than the children of a woman who chose a less genetically
fit partner,» the authors wrote.
