Respuesta:

La reproducción asexual es aquella que requiere de un único organismo, que no necesita aparearse para formar nuevos individuos. Dado que no hay intervención de células sexuales, en la reproducción sexual no hay intercambio ni combinación de información genética

Explicación:

Cuando un organismo se reproduce de manera asexual, lo hace a través de métodos que consisten en la replicación o duplicación de su contenido genético, para dar origen a individuos nuevos genéticamente idénticos a sí mismo.

Respuesta:

asexual reproduction is one that requires a single organism, which does not need to mate to form new individuals. Since there is no intervention of sex cells, there is no exchange or combination of genetic information in sexual reproduction.

When an organism reproduces asexually, it does so through methods that consist of the replication or duplication of its genetic content, to give rise to new individuals genetically identical to itself.

Reproduction consists of the production of new individuals of the same species as the parent, which makes it possible to multiply and perpetuate the species. Reproduction constitutes one of the main stages in the life cycle of every living being and, although it is not essential for an individual to survive, it is essential for a species to remain on Earth.

Organisms can reproduce in various ways, which can be grouped into two types of reproduction: sexual or asexual, depending on the number of individuals involved and whether the offspring are genetically identical to the parental organism or organisms.

Sexual reproduction, like that of human beings, involves sexual contact between two individuals, a female and a male, each of whom contributes a gamete or sex cell. The union between the female and male gametes (ovum and sperm respectively) gives rise to the embryo, which when developing will form a new individual of the same species, whose genetic material will result from the combination of those of its parents. Thus, in sexual reproduction, each parent provides half of the genetic information, and offspring are genetically different from their parents.

Asexual reproduction is typical of single-celled organisms, such as prokaryotes and protists, and is common in fungi, invertebrates, and plants. Although in the more complex forms of life, sexual reproduction is usually more frequent, there are also some specific cases of animals that reproduce asexually

Explicación:


army12743: Asexual reproduction is quick and simple, since it does not require the production of specialized cells (gametes), nor does it require expending energy to achieve fertilization, or other similar efforts. Thus, this type of reproduction allows an isolated individual to perfectly give rise to new descendants, sometimes many of them, although always genetically identical to himself and to each other.
army12743: This is particularly useful in situations of biological risk or in need of rapid expansion, for example, during the colonization of a territory or the massification of specimens in the face of imminent danger.
army12743: Disadvantages of asexual reproduction
The great disadvantage of asexual reproduction is its absence of genetic variability, that is, the fact that the offspring are identical to the parent, except in the case of unforeseen mutations.
army12743: Thus, the species evolves at a much slower and less effective rate since natural selection cannot favor the fittest individuals. This could kill a colony or even a species very quickly, since its lower genetic variability can prevent it from adapting quickly to a changing environment.
