I assume you mean "influences". In which case a female can most certainly provide masculine influences, and vice versa. Not to mention the fact that rarely - if ever - does a couple raise a child in a vacuum. There are other people in a child's life. Grandparents, aunts, uncles, cousins, sisters, brothers, friends, teachers, etc. Just because someone has only one parent, or has two parents of the same gender does NOT mean that they never see, talk to, or learn from the other gender. The idea that they are in some dark hole with just their parent or parents is pretty preposterous.
