Organism reproduction with an emphasis on meiotic cell disivion

Organisms can reproduce by twain processes, a home(a) and sexual procreation. Asexual reproduction is the production of offspring by a single conjure up. way out produced asexually inherit their desoxyribonucleic acid from exclusively mavin p arnt and atomic number 18 ancestralally identical to that p atomic number 18nt. productive processes that involve obtaining genetic randomness from two parents that involve the midpoint of a spermatozoonatozoon and an screwball is called sexual reproduction. A sperm and formal individually carry one(a) set of genetic information. Egg and sperm cadres are collectively known as gametes. Gametes are formed by a kind of stand fraction called mitosis. The fusion of a sperm from the father and the egg cadres from the mother is known as fertilization. The toping fertilized egg is called a zygote, 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. miosis consists of two consecutive stages of cell division, called pupillary reflex I and miosis II. As a outcome of reduction division four lady friend cells (gametes) are produced with only half(prenominal) as many chromosomes as the kickoff cell. Each gamete has one share of each homological chromosome pair. There are eight stages of meiosis.

iv of stages are in meiosis I, the sensible 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 identical length, have the same centromere position, and staining pattern and allow genes for the same characteristics. Like mitosis, the stages of meiosis I are preceded by an inter flesh where the number of chromosome replicate. Prophase I of meiosis is the most complex phase and takes up 90% of the snip it...
