Columbia University Press N. Ecology and evolution of sex in aphids. Every single egg or sperm may have a different selection of alleles from the parental chromosomes. Reviewing applications can be fun and only takes a few minutes. The KudoZ network provides a framework for translators and others to assist each other with translations or explanations of terms and short phrases.

In the sex cells the chromosome number is n humans: Just like mitosismeiosis includes prophase, metaphase, anaphase and telophase. Login or register free and only takes a few minutes to participate in this question. Participation is free and the site has etrecruzamiento strict confidentiality policy. Fertilization restores the chromosomes in body cells to the diploid number. But the two sets of chromosomes are not identical with the parental chromosomes.

This is because they are changed during the reduction division by a process called crossing-over.

Return to KudoZ list. You have native languages that can be verified You can request verification for native languages by completing a simple application that takes only meiosiw couple of minutes.


Patents, Trademarks, Copyright Law: From Wikipedia, the free encyclopedia. This system of reproduction is called apogamy. Cada quiasma se origina en un sitio de entrecruzamiento, lugar en el que anteriormente se rompieron dos cromatidas hermanas que intercambiaron material Review native language verification applications submitted by your peers.

The two cells prepare netrecruzamiento divide again in a stage known as interkinesis or interphase II. In entrecruzakiento projects Wikimedia Commons. When meiosis occurs, crossing-over produces a genetic fingerprint which differs somewhat from the mother’s. This also includes many single-celled organisms. Crossing-over changes which entrecruzzamiento sit on a particular chromosome.

The shuffling of alleles which takes place in meiosis may be the reason why sexual reproduction exists at all. At the end of the season, when the weather gets worse, they use sexual reproduction.

Salloz KudoZ activity Questions: Retrieved from ” entrecruza,iento View Ideas submitted by the community. Explain the causes of genetic recombination, particularly the inheritance of linked traits and results of crossing over during meiosis.

Comparación entre mitosis y meiosis

Views Read Change Change source View history. These include the Bdelloid rotiferswhich only reproduce by parthenogenesis. Although the gametes have only one set of chromosomes, that set is a shuffled mixture of genetic material from both parents.

In parthenogenesis, the eggs contain only the mother’s genetic material, and they are not fertilized. Several quite large taxa groups of organisms use cyclical parthenogenesis.

This is when several generations are born by virgin birth, and then a generation occurs with normal sexual reproduction. All eukaryotes that reproduce sexually use meiosis.


The offspring gets a set of chromosomes from each parent so that, overall, half of its heredity comes from each parent. Post Your ideas for ProZ. The only exception are the sex chromosomes. See Terms of Use for details. Meiosis does not occur in archaea or bacteriawhich reproduce by asexual processes such as binary fission. The function of the first division is to permit crossing over.

To allow crossing-over to take place between each pair of parental chromosomes. Term search All of ProZ. Notes to answerer Asker: In malesall four cells become sperm.

Examples include aphidsand cladocerans small crustacea called water fleas. The growth of biological thought: English term or phrase: Respuestas – Cual es el resultado de la primera division In femalesonly one becomes a mature egg, while the remaining three become re-absorbed into the body.
