  • Reproduction (or procreation or breeding) is the biological process by which new individual organisms – "offspring" – are produced from their "parents". Reproduction is a fundamental feature of all known life; each individual organism exists as the result of reproduction. There are two forms of reproduction: asexual and sexual. Other ways of asexual reproduction include.

Apomixis importance for tropical forage grass selection and breeding. Quero Carrillo a , Javier F. Correspondencia al primer autor. Individuos diploides mantienen la sexualidad activa y estos son raros fuera del centro de origen de especie.

Apomixis is a reproductive system resulting in seed production without gametes fusion, and produces, through generations, offspring that is a genetic copy from the maternal progenitor. Apomixis importance is widespread among tropical grasses: Apomictic species contain diploid as well as polyploid individuals conforming "agamic complexes" and reproductive barriers limited both by apomixis as well as ploidy level which has a great impact on apomictic species utilization.

Diploid individuals maintain active the sexuality and these are rare out of the center of specie's genetic origin center.

Parthenogenesis in Komodo dragons. Parthenogenesis , the production of offspring without fertilization by way of a male, is rare in vertebrate species, which usually reproduce after fusion of male and female gametes.

Here we acquisition genetic fingerprinting to recognize empathize with parthenogenetic offspring produced aside two female Komodo dragons Varanus komodoensis that had been kept at disjoined institutions and isolated from males; one of these females subsequently produced additional offspring sexually.

This reproductive plasticity indicates that female Komodo dragons may rod between asexual and lustful reproduction, depending on the availability of a mate--a finding that has implications for the breeding of this threatened species in captivity.

Most zoos guard only females, with males being moved between zoos for mating, but possibly they should be kept together to avoid triggering parthenogenesis and thereby decreasing genetic diversity. Occurrence of Parthenogenesis in Potato Tuber Moth. Abstract Parthenogenesis Explicit, a natural form of asexual reproduction produced from unfertilized eggs, occurs in many insects in Hemiptera and Hymenoptera, but really rarely in Lepidoptera.

The current study aimed to test the larval density dependent occurrence of parthenogenesis in potato tuber moth, Phthorimaea operculella Zeller; Lepidoptera: Gelechiidae under laboratory conditions.
