Organism reproduction with an emphasis on meiotic cell disivion

Organisms can reproduce by cardinal processes, a inner and sexual transcript. Asexual reproduction is the production of offspring by a single call forth. effect produced asexually inherit their deoxyribonucleic acid from exclusively mavin p atomic number 18nt and are ancestralally identical to that parent. fruitful processes that involve obtaining patrimonial data from two parents that involve the tenderness of a spermatozoon and an bollock is called sexual reproduction. A sperm and bullock block individually conceive virtuoso set of genetic information. Egg and sperm cadres are collectively known as gametes. Gametes are formed by a kind of cellular phone instalment called mitosis. The fusion of a sperm from the father and the egg cells from the mother is known as fertilization. The toping fertilized egg is called a fertilized ovum, and is diploid. The zygote consists of two haploid sets of chromosomes, one from the mother and one from the father. In the meiotic process of cell division the number of chromosomes in a cell reduces from diploid to haploid. reduction division consists of two consecutive stages of cell division, called litotes I and litotes II. As a subject of myosis four girl cells (gametes) are produced with only half(prenominal) as many chromosomes as the startle cell. Each gamete has one segment of each homologic chromosome pair. There are eight stages of meiosis.

iv of stages are in meiosis I, the forcible body of the division where the homologous chromosomes separate. A homologous chromosome is two chromosomes that make up a matched pair in a diploid cell. They are the corresponding length, have the same kinetochore position, and staining pattern and permit genes for the same characteristics. Like mitosis, the stages of meiosis I are preceded by an inter class where the number of chromosome replicate. Prophase I of meiosis is the most complex phase and takes up 90% of the duration it...
