Meiosis in males vs Meiosis in females
Reproduction is a very important procedure necessary because that the continuation of the progeny. Sexual and asexual reproductions room the 2 different varieties of methods whereby plants and also animals reproduce. Asexual reproduction is the form of reproduction in i beg your pardon young ones space born indigenous a single parent. In sexual reproduction, both the male and also the female gametes unite to form offspring. Mitosis and meiosis space the two important steps that cell department that command to development of brand-new life.

Meiosis is a special type of reproduction i m sorry is used by humans, animals and details plants. Meiosis occurs in two different stages, meiosis 1 and also meiosis 2. In human males, meiosis wake up in the seminiferous tubules of the testicles when in females, it wake up in cells referred to as as oogonia. In males, meiosis wake up at puberty if in females it occurs best at birth. The retinoic acid developed by the primitive kidneys stimulates the procedure of meiosis in females in ~ birth, yet in males this development of retinoic mountain is suppressed till puberty by the organization of the testis. This suppression is overcome once at puberty the sertoli cell start producing retinoic mountain on their own. This is a an extremely important distinction in the steps of meiosis in males and also females.
In meiosis 1, there is splitting of the gametes into two in such a method that over there is palliation in the variety of chromosomes to fifty percent of what is current originally in parental cell. Initially, there is crossing over of chromosomes acquired from the parental cells which help in mix the attributes from each parent, and also then fifty percent of the complete chromosomes acquire distinctly separated indigenous the other. All the chromosomes get equally distributed in halves; hence, they additionally carry characteristics of their parental cells in same proportion. This action is likewise called as ‘reductional division’ as throughout the procedure of division, chromosomes reduce to fifty percent the number than initially present. Following step is meiosis 2; in this stage there is internal separating of one half of the daughter cells and what we gain is 4 daughter cell with various permutation and mix of the chromosomes.
Meiosis is vital in mammals due to the fact that when the male and also the woman gametes fuse to form the zygote, then throughout the formation of the zygote there is instead of of the lost number of chromosomes to gain back the number come the original 42 chromosomes. If throughout meiosis 1 or meiosis 2, there is an error throughout division, such the there is one extra chromosome or one chromosome less, then it is termed together non-disjunction. If over there is non-disjunction, climate it will certainly lead to development of zygotes with extra chromosomes and also will cause the birth of a child with many anomalies or also mental retardation. Therefore, meiosis is a an extremely important action in reproduction. The daughter cells created by woman gametes bring only the X sex chromosome if the daughter cells developed by masculine gametes lug either one X or Y sex chromosomes. As a matter of fact, meiosis is necessary for development of the zygote yet once the zygote is formed it grows additional to become a fetus by mitotic cell division. Mitosis is plain replication that the cell by maintaining the chromosome number intact as the parental cells.

Summary: Meiosis occurs at birth in females in oogonia cells yet occurs in ~ puberty in males in the seminiferous tubules. Meiosis is a procedure of cell replication where there is palliation of the variety of chromosomes to fifty percent from the original.
