  2. Parental care - Wikipedia

    en.wikipedia.org/wiki/Parental_care

    Parental care is a behavioural and evolutionary strategy adopted by some animals, involving a parental investment being made to the evolutionary fitness of offspring. Patterns of parental care are widespread and highly diverse across the animal kingdom. [1] There is great variation in different animal groups in terms of how parents care for ...

  3. Reproduction - Wikipedia

    en.wikipedia.org/wiki/Reproduction

    Reproduction (or procreation or breeding) is the biological process by which new individual organisms – "offspring" – are produced from their "parent" or parents. There are two forms of reproduction: asexual and sexual. In asexual reproduction, an organism can reproduce without the involvement of another organism.

  4. Heredity - Wikipedia

    en.wikipedia.org/wiki/Heredity

    Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.

  5. Paternal care - Wikipedia

    en.wikipedia.org/wiki/Paternal_care

    Paternal care. In biology, paternal care is parental investment provided by a male to his own offspring. It is a complex social behaviour in vertebrates associated with animal mating systems, life history traits, and ecology. [1] Paternal care may be provided in concert with the mother (biparental care) or, more rarely, by the male alone (so ...

  6. Offspring - Wikipedia

    en.wikipedia.org/wiki/Offspring

    Genetics. In biology, offspring are the young creation of living organisms, produced either by sexual or asexual reproduction. Collective offspring may be known as a brood or progeny. This can refer to a set of simultaneous offspring, such as the chicks hatched from one clutch of eggs, or to all offspring produced over time, as with the honeybee.

  7. Parthenogenesis - Wikipedia

    en.wikipedia.org/wiki/Parthenogenesis

    This is the first recognized example of an animal species where both females and males can reproduce clonally resulting in a complete separation of male and female gene pools. [60] As a consequence, the males will only have fathers and the queens only mothers, while the sterile workers are the only ones with both parents of both sexes.

  8. Kin selection - Wikipedia

    en.wikipedia.org/wiki/Kin_selection

    Kin selection is a process whereby natural selection favours a trait due to its positive effects on the reproductive success of an organism's relatives, even when at a cost to the organism's own survival and reproduction. [ 1 ] Kin selection can lead to the evolution of altruistic behaviour. It is related to inclusive fitness, which combines ...

  9. Parental investment - Wikipedia

    en.wikipedia.org/wiki/Parental_investment

    A human mother feeding her child. Parental investment, in evolutionary biology and evolutionary psychology, is any parental expenditure (e.g. time, energy, resources) that benefits offspring. [1][2] Parental investment may be performed by both males and females (biparental care), females alone (exclusive maternal care) or males alone (exclusive ...
