Extensive Definition

A parent is a father or mother; one who sires or gives birth to and/or nurtures and raises an offspring. The different role of parents varies throughout the tree of life, and is especially complex in human culture.

Mother

A mother is the biological or social female parent of a child or offspring. The maternal bond describes the feelings the mother has for her (or another's) child. In the case of a mammal such as a human, the mother gestates her child (called first an embryo, then a fetus) in the uterus from conception or implantation until the fetus is sufficiently well-developed to be born. The mother then goes into labour and gives birth. Once the child is born, the mother produces milk to feed the child.

Father

A father is traditionally the male parent. Like mothers, fathers may be categorised according to their biological, social or legal relationship with the child. Historically, the biological relationship paternity has been determinative of fatherhood. However, proof of paternity has been intrinsically problematic and so social rules often determined who would be regarded as a father e.g. the husband of the mother.

Biological parents and parental testing

The term biological parent refers to a parent who is the biological mother or father of an individual. While an individual's parents are often also their biological parents, it is seldom used unless there is an explicit difference between who acted as a parent for that individual and the person from whom they inherit half of their genes. For example, a person whose father has remarried may call his new wife their stepmother and continue to refer to their mother normally, though someone who has had little or no contact with their biological mother may address their foster parent as their mother, and their biological mother as such, or perhaps by her first name.

Parental testing

A paternity test is conducted to prove paternity, that is, whether a man is the biological father of another individual. This may be relevant in view of rights and duties of the father. Similarly, a maternity test can be carried out. This is less common, because at least during childbirth and pregnancy, except in the case of a pregnancy involving embryo transfer or egg donation, it is obvious who the mother is. However, it is used in a number of events such as legal battles where a person's maternity is challenged, where the mother is uncertain because she has not seen her child for an extended period of time, or where deceased persons need to be identified.
Although not constituting completely reliable evidence, several congenital traits such as attached earlobes, the widow's peak, or the cleft chin, may serve as tentative indicators of (non-)parenthood as they are readily observable and inherited via autosomal-dominant genes.
A more reliable way to ascertain parenthood is via DNA analysis (known as genetic fingerprinting of individuals, although older methods have included ABO blood group typing, analysis of various other proteins and enzymes, or using HLA antigens. The current techniques for paternity testing are using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). For the most part however, DNA has all but taken over all the other forms of testing.

Parent-offspring conflict

Parent-offspring conflict describes the evolutionary conflict arising from differences in optimal fitness of parents and their offspring. While parents tend to maximize the number of offspring, the offspring can increase their fitness by getting a greater share of parental investment often by competing with their siblings. The theory was proposed by Robert Trivers in 1974 and extends the more general selfish gene theory and has been used to explain many observed biological phenomena. For example, in some bird species, although parents often lay two eggs and attempt to raise two or more young, the strongest fledgling takes a greater share of the food brought by parents and will often kill the weaker sibling, an act known as siblicide.
David Haig has argued that human fetal genes would be selected to draw more resources from the mother than it would be optimal for the mother to give, an hypothesis that has received empirical support. The placenta, for example, secretes allocrine hormones that decrease the sensitivity of the mother to insulin and thus make a larger supply of blood sugar available to the fetus. The mother responds by increasing the level of insulin in her bloodstream, the placenta has insulin receptors that stimulate the production of insulin-degrading enzymes which counteract this effect.
