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 .
When this occurs, a male-female pair is over twice as successful in nest defense, preventing the ovicide of their offspring. Female langurs may leave the group with their young alongside the outgoing male, and others may develop a false estrous and allow the male to copulate, deceiving him into thinking she is actually sexually receptive.

Infanticide (or infant homicide) is the intentional killing of infants or offspring. Infanticide was a widespread practice throughout human history that was mainly used to dispose of unwanted children, [1]: 61 its main purpose being the prevention of resources being spent on weak or disabled offspring.
O-Six (named after the year of her birth). [3] was for several years [2010 - 2012] the dominant breeding female of the Lamar Canyon pack in Yellowstone National Park.Born in 2006 in the Agate Creek pack to Agate Creek Wolves #113M (born a Chief Joseph Wolf in 1997) and Wolf #472F (born a Druid Peak wolf in 2000), [4] [5] [6] she was principally known by the year of her birth.

In population ecology and demography, the net reproduction rate, R 0, is the average number of offspring (often specifically daughters) that would be born to a female if she passed through her lifetime conforming to the age-specific fertility and mortality rates of a given year.
This is an accepted version of this page This is the latest accepted revision, reviewed on 4 March 2025. This is a list of notable offspring of a deity with a mortal, in mythology and modern fiction. Such entities are sometimes referred to as demigods, although the term "demigod" can also refer to a minor deity, or great mortal hero with god-like valour and skills, who sometimes attains divine ...
In 2004, by altering the function of a few genes involved with imprinting, other Japanese scientists combined two mouse eggs to produce daughter mice [24] and in 2018 Chinese scientists created 29 female mice from two female mice mothers but were unable to produce viable offspring from two father mice. Researches noted that there is little ...
In genetics, a maternal effect occurs when the phenotype of an organism is determined by the genotype of its mother. [1] For example, if a mutation is maternal effect recessive, then a female homozygous for the mutation may appear phenotypically normal, however her offspring will show the mutant phenotype, even if they are heterozygous for the mutation.
