Information:  - Rights are legal, social, or ethical principles of freedom or entitlement; that is, rights are the fundamental normative rules about what is allowed of people or owed to people, according to some legal system, social convention, or ethical theory. Rights are of essential importance in such disciplines as law and ethics, especially theories of justice and deontology. Rights are often considered fundamental to civilization, being regarded as established pillars of society and culture, and the history of social conflicts can be found in the history of each right and its development. According to the "Stanford Encyclopedia of Philosophy", "rights structure the form of governments, the content of laws, and the shape of morality as it is currently perceived".  - A mother is the female parent of a child. Mothers are women who inhabit or perform the role of bearing some relation to their children, who may or may not be their biological offspring. Thus, dependent on the context, women can be considered mothers by virtue of having given birth, by raising their child(ren), supplying their ovum for fertilisation, or some combination thereof. Such conditions provide a way of delineating the concept of motherhood, or the state of being a mother. Women who meet the third and first categories usually fall under the terms 'birth mother' or 'biological mother', regardless of whether the individual in question goes on to parent their child. Accordingly, a woman who meets only the second condition may be considered an adoptive mother, and those who meet only the third a surrogacy mother.  - A paternal bond refers to the relationship between a father and his child . In the U.S. , legal paternity is presumed for the husband of the mother unless a separate action is taken ; an unmarried man may establish paternity by signing a voluntary recognition of paternity or by taking court action . Paternity may also be established between a man and a younger person , commonly in adoption , without the two being biologically related .  - Sperm donation is the provision (or "donation") by a male (known as a sperm donor) of his sperm (known as donor sperm), principally for the purpose of inseminating a female who is not his sexual partner.  - Sexual intercourse, or coitus or copulation, is principally the insertion and thrusting of the penis, usually when erect, into the vagina for sexual pleasure, reproduction, or both. This is also known as vaginal intercourse or vaginal sex. Other forms of penetrative sexual intercourse include anal sex (penetration of the anus by the penis), oral sex (penetration of the mouth by the penis or oral penetration of the female genitalia), fingering (sexual penetration by the fingers), and penetration by use of a dildo (especially a strap-on dildo). These activities involve physical intimacy between two or more individuals and are usually used among humans solely for physical or emotional pleasure and commonly contribute to human bonding.  - Inheritance is the practice of passing on property, titles, debts, rights, and obligations upon the death of an individual. The rules of inheritance differ between societies and have changed over time.  - Biologically, a child (plural: children) is a human being between the stages of birth and puberty. The legal definition of "child" generally refers to a minor, otherwise known as a person younger than the age of majority.  - A father is the male parent of a child. Besides the paternal bonds of a father to his children, the father may have a parental legal and social relationship with the child that carries with it certain rights and obligations, although this varies between jurisdictions. An adoptive father is a male who has become the child's parent through the legal process of adoption. A biological father is the male genetic contributor to the creation of the baby, through sexual intercourse or sperm donation. A biological father may have legal obligations to a child not raised by him, such as an obligation of monetary support. A putative father is a man whose biological relationship to a child is alleged but has not been established. A stepfather is a male who is the husband of a child's mother and they may form a family unit, but who generally does not have the legal rights and responsibilities of a parent in relation to the child.  - A male () organism is the physiological sex that produces sperm. Each spermatozoon can fuse with a larger female gamete, or ovum, in the process of fertilization. A male cannot reproduce sexually without access to at least one ovum from a female, but some organisms can reproduce both sexually and asexually. Most male mammals, including male humans, have a Y chromosome, which codes for the production of larger amounts of testosterone to develop male reproductive organs.  - Parenting or child rearing is the process of promoting and supporting the physical, emotional, social, financial, and intellectual development of a child from infancy to adulthood. Parenting refers to the aspects of raising a child aside from the biological relationship.  - Filiation is the legal term that refers to the recognized legal status of the relationship between family members, or more specifically the legal relationship between parent and child. As described by the Government of Quebec:  - Sperm is the male reproductive cell and is derived from the Greek word () "sperma" (meaning "seed"). In the types of sexual reproduction known as anisogamy and its subtype oogamy, there is a marked difference in the size of the gametes with the smaller one being termed the "male" or sperm cell. A uniflagellar sperm cell that is motile is referred to as a spermatozoon, whereas a non-motile sperm cell is referred to as a spermatium. Sperm cells cannot divide and have a limited life span, but after fusion with egg cells during fertilization, a new organism begins developing, starting as a totipotent zygote. The human sperm cell is haploid, so that its 23 chromosomes can join the 23 chromosomes of the female egg to form a diploid cell. In mammals, sperm develops in the testicles and is released from the penis. It is also possible to extract sperm through TESE. Some sperm banks hold up to of sperm.  - Adoption is a process whereby a person assumes the parenting of another, usually a child, from that person's biological or legal parent or parents, and, in so doing, permanently transfers all rights and responsibilities, along with filiation, from the biological parent or parents. Unlike guardianship or other systems designed for the care of the young, adoption is intended to effect a permanent change in status and as such requires societal recognition, either through legal or religious sanction. Historically, some societies have enacted specific laws governing adoption; where others have tried to achieve adoption through less formal means, notably via contracts that specified inheritance rights and parental responsibilities without an accompanying transfer of filiation. Modern systems of adoption, arising in the 20th century, tend to be governed by comprehensive statutes and regulations.    What entity does 'paternal bond' has the relation 'subclass of' with?
The answer to this question is:
human bonding
