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 .
Animals with few offspring can devote more resources to the nurturing and protection of each individual offspring, thus reducing the need for many offspring. On the other hand, animals with many offspring may devote fewer resources to each individual offspring; for these types of animals it is common for many offspring to die soon after birth ...
Plant reproduction is the production of new offspring in plants, which can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion of gametes, resulting in offspring genetically different from either parent.

One fish species does not reproduce by sexual reproduction but uses sex to produce offspring; Poecilia formosa is a unisex species that uses a form of parthenogenesis called gynogenesis, where unfertilized eggs develop into embryos that produce female offspring.
Here, offspring are produced by the same mechanism as in parthenogenesis, ... The theme is one of several aspects of reproductive biology explored in science fiction.
The offspring produced in androgenesis will still have maternally inherited mitochondria, as is the case with most sexually reproducing species. Androgenesis occurs in nature in many invertebrates (for example, clams, [ 34 ] stick insects, [ 35 ] some ants, [ 36 ] bees, [ 37 ] flies [ 38 ] and parasitic wasps [ 37 ] ) and vertebrates (mainly ...
The specific problem is: due to unclear definitions for fertility, fecundity and derivative terms depending on whether the term is being used in demography, epidemiology or clinical medicine. For example fecundity is the potential to for a female to become pregnant and carry that pregnancy to a live birth in demography, while in clinical ...
