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 ...
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.
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.
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 ...
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.
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.
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 ...
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 ...
