Meiosis in males vs Meiosis in females
Reproduction is a very important process necessary because that the continuation of the progeny. Sexual and asexual reproductions are the 2 different species of methods whereby plants and animals reproduce. Asexual reproduction is the form of reproduction in i beg your pardon young ones are born native a single parent. In sex-related reproduction, both the male and the mrs gametes hold together to kind offspring. Mitosis and also meiosis room the two important steps of cell department that command to development of new life.
You are watching: Which of the following best describes the process of meiosis?
Meiosis is a special type of reproduction which is offered by humans, pets and particular plants. Meiosis occurs in two various stages, meiosis 1 and meiosis 2. In human males, meiosis wake up in the seminiferous tubules the the testicles if in females, it wake up in cells called as oogonia. In males, meiosis occurs at puberty if in females the occurs ideal at birth. The retinoic acid developed by the primitive kidney stimulates the process of meiosis in females in ~ birth, but in males this formation of retinoic acid is suppressed it spins puberty by the tissues of the testis. This suppression is overcome when at puberty the sertoli cell start creating retinoic acid on their own. This is a really important distinction in the procedures of meiosis in males and also females.
In meiosis 1, there is dividing of the gametes right into two in such a method that over there is palliation in the variety of chromosomes to half of what is current originally in parental cell. Initially, there is crossing end of chromosomes obtained from the parent cells which help in mix the features from every parent, and then half of the complete chromosomes gain distinctly separated from the other. Every the chromosomes get equally distributed in halves; hence, they likewise carry properties of their parent cells in equal proportion. This step is likewise called together ‘reductional division’ as throughout the process of division, chromosomes minimize to fifty percent the number than originally present. Next step is meiosis 2; in this phase there is internal splitting of one half of the daughter cells and what we gain is four daughter cell with various permutation and mix of the chromosomes.
Meiosis is vital in mammals because when the male and also the woman gametes fuse to kind the zygote, then during the formation of the zygote there is replacement of the lost number of chromosomes to reclaim the number come the original 42 chromosomes. If throughout meiosis 1 or meiosis 2, over there is one error during division, such that there is one extra chromosome or one chromosome less, then it is termed together non-disjunction. If over there is non-disjunction, then it will certainly lead to formation of zygotes v extra chromosomes and will bring about the birth of a kid with countless anomalies or even mental retardation. Therefore, meiosis is a really important step in reproduction. The daughter cells created by woman gametes carry only the X sex chromosome if the daughter cells developed by male gametes bring either an X or Y sex chromosomes. Together a issue of fact, meiosis is necessary for formation of the zygote but once the zygote is created it grows more to become a fetus by mitotic cell division. Mitosis is plain replication that the cells by keeping the chromosome number undamaged as the parental cells.

Summary: Meiosis occurs at birth in females in oogonia cells however occurs in ~ puberty in males in the seminiferous tubules. Meiosis is a process of cabinet replication wherein there is palliation of the variety of chromosomes to half from the original.
